Which of these waves has the highest frequency?

• 1

• 2

• 3

A mechanical wave requires a ________.

• Motion
• Medium
• Vacuum
• Car

What is the Doppler Effect?

• A change in frequency due to the relative motion of a wave source and an observer

• When a wave overlaps with another wave

• When a wave bounces off of another object

• When a wave bends due to traveling through a different medium

Light can change color due to the Doppler Effect.

• True

• False

Look at the picture. Who is experiencing a higher pitched sound?

• Observer A

• Observer B

• There's no difference

when the frequency is higher what happens to the wavelength?

• the wavelength gets longer

• The wavelength gets shorter

• the wavelength doesn't change

• I have no idea
