1. Draw a model of a sound wave using dots to represent particles. Label compressions, rarefactions, and wavelength.
2. Compare sound waves to wind.
3. Describe how the movement of a speaker changes when the volume is increased. What characteristic of the sound wave produced by the speaker changes?
4. Draw a model of a transverse wave. Label wavelength, crest, trough, resting position, and amplitude.
5. Why do you think sound waves are shown as transverse waves on oscilloscope screens when they are actually longitudinal waves?
6. Explain how and why the speed of a wave can change.
7. How do the frequencies of two sound waves traveling through air compare if the wavelength of one of the waves is five times that of the other wave?
8. Water drops falling from a leaky faucet into a bathtub begin to fall at a faster rate than before. When the drops fall faster, does the speed of the waves in the bathtub change?
9. Explain how and why amplitude and frequency are both related to the energy of a wave.
10. Compare sound waves and light waves.
11. Draw a model of light traveling through a prism and explain how the prism separates white light into different colors.
12. Explain the cause of skin cancer and how ozone and melanin protect people from UV light.
13. How are “grow lights” better in some ways than natural sunlight for plants?
14. Does a green leaf use green light for photosynthesis? Explain.
15. What colors does a white piece of paper reflect? Why can’t you see your reflection on the paper?

Please help I got a C in science (I know I suck) and I need to pass this test in order to get my phone back-
If you can answer it in really easy explanations
