1. What phenomenon describes the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source?
Refraction
Diffraction
Doppler Effect
Interference
2. When an ambulance with its siren on approaches you, what happens to the pitch of the siren?
It gets lower.
It gets higher.

1. The Doppler Effect is observed for both sound waves and waves.
2. When a wave source moves away from an observer, the observed frequency will be than the emitted frequency.
3. Redshift is an example of the Doppler Effect applied to radiation, indicating objects are moving away from us.
1. The Doppler Effect only occurs when the source of the wave is moving, not the observer.
True
False
2. A blueshift indicates that a light source is moving towards the observer.
True
False
1. Describe one real-world application of the Doppler Effect.
2. Explain why the perceived pitch of a sound changes as a moving source passes a stationary observer.
