What is the doppler effect?

• a change in the frequency of sound, light or other waves to cause a change in pitch

• A change in pitch that causes frequency, sound, light and other waves to disappear

• I have no idea

• A change in sound that alters frequency

when a noise is moving towards an observer, the closer it comes...

• the lower the pitch

• the longer the noise

• the higher the pitch

• the quieter the noise

the doppler effect causes a shift in...

• pitch

• wavelength

• frequency

• All of the above

when a noise if moving away from an observer...

• the pitch is lower

• the pitch is higher

• the noise is smoother

• the energy is lower

As objects move in space, their wavelengths change. This phenomenon is called the...

• Coriolis Effect

• Doppler Effect

• Movement Effect

• Black Hole Effect

The pitch of a sound wave relates to the wave's _________________.

• Amplitude

• Frequency

• Wavelength

• Period

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
