In the lesson you will:
• explain that light waves can be reflected, refracted, and/or absorbed
• recognize that light waves move in straight lines unless they travel into a transparent material, or medium, which may cause the light wave to bend
• differentiate light waves and matter waves
Big Ideas:
Key Questions and Terms Notes
The way that light waves interact with different mediums is called the ________.
When does reflection occur?
Light reflects off of the medium at a ________ angle to which it initially struck the material. This means that if the light hits a mirror at a 40-degree angle, it will bounce off at a ___ degree angle. Draw a picture of what this looks like.
When does refraction occur?
When light can pass through an object, it is called ________.
When does absorption occur?

How are electromagnetic waves different from matter waves?
Would outer space be an ideal spot for a concert? Why or why not?
________ waves need to interact with particles of either a solid, liquid, or gas to travel.
Light Waves and Sound Waves
Record your findings of sound and light waves for each of the following.
• Traveling through air
• Traveling through metal
• Why light travels faster
Answer:
The way that light waves interact with different mediums is called the refraction.
When does reflection occur?: It occurs when light waves collide with a medium, causing the light waves to bounce off. The light reflects off the medium at a similar angle to which it initially stuck the material
Light reflects off of the medium at a 40 degree angle to which it initially struck the material. This means that if the light hits a mirror at a 40-degree angle, it will bounce off at a 40 degree angle. Draw a picture of what this looks like. (you'll have to draw the picture by yourself)
When does refraction occur?: It occurs when light travels through a transparent medium, causing them to bend and change direction. AS the light passes from air into water, it bends.
When light can pass through an object, it is called transmission.
When does absorption occur?: It occurs when light waves strike a medium and are neither reflected or refracted, nor are allowed to pass through.
Describe how visible light interacts with these materials:
• Mirror: Visible white light that is directed onto the surface of a mirror at an angle (incident) is reflected back into space by the mirror surface at another angle (reflected) that is equal to the incident angle, as presented for the action of a beam of light from a flashlight on a smooth, flat mirror.
• Glass of water: The light travels straight through the glass, but the direction it is traveling bends when entering and leaving the object.
• Dark fabric: Dark objects (fabric) absorb those wavelengths, and lighter objects reflect more. The temperature of the black fabrics shown in visible and near-infrared (shown on the left) over time.
What are some examples of matter waves?: Sound waves, waves in a Slinky, and water waves are all examples of this.
What are some examples of electromagnetic waves?: Gamma rays, light waves, wireless waves, & X-rays are examples.
How are electromagnetic waves different from matter waves?: The main difference between electromagnetic waves and matter waves is in the components that make them. Also, there is no need for sound radiation to pass through a medium/requirement to communicate with other particles to travel like waves of matter.
Would outer space be an ideal spot for a concert? Why or why not?: (you can change this depending on your opinion) No, it wouldn't. There is no oxygen up in outer space, as well as gravity to keep the people, as well as the instruments grounded. The likelyhood of floating away is very high, so, as soon as you get there you wouldn't be able to see the concert at all.
Matter waves need to interact with particles of either a solid, liquid, or gas to travel.
Record your findings of sound and light waves for each of the following.
• Traveling through air: The light waves pass thru the air more quickly than sound waves.
• Traveling through metal: Sound waves almost always go through a metal frame.
• Why light travels faster: Light waves travel faster than electrical signals even though they don't have to crash in electromagnetic waves to particles.

While most other organisms obtain energy from food, plants get their energy from the sun. Would you support research to genetically modify humans to be able to use photosynthesis for part of our energy and reduce the amount of food we need?
It is not possible to perform research on genetically modify humans that use photosynthesis for part of our energy and reduce the amount of food we need.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food with the help of carbon dioxide and water in the presence of sunlight.
If humans are genetically modified in such a way that they trap the radiation from the sun and synthesize their own food, the ecological balance of the whole planet may get disturbed. Food chains can not run systematically.
There must be no differentiation between plants and humans. The level of oxygen suddenly increases, while the amount of carbon dioxide reduces. As a result of this, plants gradually become extinct.
Therefore, I would not support the research that involves the genetic modification of humans to use photosynthesis for part of our energy and reduce the amount of food we need.

Explanation:
Cellular respiration is a place in the cells of organisms to convert chemical energy from oxygen or nutrients into adenosine triphosphate which is the main carrier for energy in cells. so this is how cells release stored energy to the body when there is no oxygen.
Which type of plant existed the longest in earth history, ferns, gymnosperms, or angiosperms?
I'm giving a lot of points for this and I will also give brainliest if its detailed and well explained! ^^
Explanation:
The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats, through multicellular marine and freshwater green algae, terrestrial bryophytes, lycopods and ferns, to the complex gymnosperms and angiosperms (flowering plants) of today. While many of the earliest groups continue to thrive, as exemplified by red and green algae in marine environments, more recently derived groups have displaced previously ecologically dominant ones; for example, the ascendance of flowering plants over gymnosperms in terrestrial environments.
There is evidence that cyanobacteria and multicellular photosynthetic eukaryotes lived in freshwater communities on land as early as 1 billion years ago, and that communities of complex, multicellular photosynthesizing organisms existed on land in the late Precambrian, around 850 million years ago.

The suggested ratio for the time of inhalation to exhalation when using breath control as a relaxation device is.
The suggested ratio for inspiration and expiration time during normal spontaneous breathing is 1:1.5 to 1:2 s with an inspiratory time of 0.8 to 1.2 s.
How to calculate inspiratory time?The inspiratory time can be calculated by dividing the tidal volume by the inspiratory flow. Thus, decreasing the VT or increasing the inspiratory flow, there is a decrease in the inspiratory time.
With this information, we can conclude that the suggested ratio for inspiration and expiration time during normal spontaneous breathing is 1:1.5 to 1:2s with an inspiratory time of 0.8 to 1.2 s. During mechanical ventilation, it will depend on the tidal volume, respiratory rate, inspiratory flow and inspiratory pause.

Based on what you learned in the lab, why does your body need to break down starch into glucose? starch contains more energy than glucose. starch molecules are too large to diffuse into cells. glucose molecules are larger than starch molecules.
Answer:
Starch molecules are too large to diffuse into
cells.
Explanation:
just did it
Your body needs to break down starch into glucose because starch molecules are too large to diffuse into cells. The size of the starch molecule is too large to pass through the cell membrane and into the cell where it is needed.
What is Starch?Starch is a complex carbohydrate made up of many glucose molecules bonded together in a long chain. When we consume starch, our digestive system breaks it down into individual glucose molecules, which can be absorbed into the bloodstream and used by cells for energy.
The starch molecule must first be broken down into its individual glucose units, which are small enough to pass through the cell membrane and be used for energy.
So, while it is true that starch contains more energy per molecule than glucose, and glucose molecules are actually smaller than starch molecules, the primary reason why our bodies need to break down starch into glucose is because of the size of the starch molecule itself.

A state agency wants to release endangered hawks but needs to determine the best site for their release. The state would like to know how many rabbits are in each area to determine which area has the largest prey population. Create a plan to determine how many rabbits are in each area to determine which site is the best location. Your plan should include specific information on how many animals will be tagged and how many samples should be taken to get the most accurate results. Use your simulation data to help you develop this plan
Given the image of the area in which the hawks needed to be released, the site A being the largest is best suited for releasing the population of hawks, followed by site C and then site B.
Site A should have the biggest sampling size for rabbits because it has the largest area, followed by Site C and Site B.
Plan to estimate the number of rabbits at various locations
The method of marking and recapture involves bringing in some rabbits again nearby and marking them. They will occasionally be recaptured, but the quantity should be more than the prior sampling size. The potential number of rabbits will be calculated using the ark recapture algorithm.
The direct count approach requires that potential regions inside the sites where there will be a greater likelihood of finding rabbits be marked out, and it then involves direct counting for a specific period of time at a specific interval. Every sample location needs to follow this procedure.
The use of camera traps might be suggested as a strategy to discover variety. Many cameras need to be set up at the potential locations so that they may take pictures to help identify.
It is possible to count pellets to determine the precise number of rabbits. Nevertheless, because DNA collection is necessary, this procedure is expensive.
The population of a species in a given location at a given period is not, however, determined by a variety of circumstances. Hence, a site may have any number of people, regardless of size.
From the following methods, diversity and the prey population can be determined. But site A having more area is considered to contain more prey population.
