Unit 6 test: Waves

Waves move energy not matter.

What is the distance from one compression to the next in a longitudinal wave?

On a longitudinal wave, in which areas are particles farthest apart?

Surface ripples on a pond are an example of what type of wave?

If

then, what is

If the wavelength of a transverse wave is 0.5 m and the frequency is 2 Hz, what is the waves velocity? (Make sure to include the correct unit!)

If the velocity of a wave is 20 m/s and the frequency of the wave is 4 Hz, what is its wavelength?

What type of reflection causes fiber optics to work?

What does the Law of Reflection state?

All of the colors are in white light, they are just all mixed up. To see all the colors separately, you can use a prism.

Order these colors from the highest index of refraction to the lowest index of refraction. The index of refraction is based on which colors get bent the most through a prism.

Explain the Doppler Effect (in your own words).

What is pitch?

X-Rays and Gamma Rays are harmful to humans, so medical professionals use them sparingly in medical imaging and to kill cancer cells.

Extra Credit: Explain why you can use radio waves to communicate with satellites beyond Earth's atmosphere.

Extra Credit: List the visible light spectrum in order from the lowest frequency to highest frequency.
