What best describes the doppler effect?

An apparent change in frequency of a wave due to the relative motion between a wave source and an observer

An apparent change in the amplitude of a wave due to the relative motion between a wave source and an observer.

When you hear a motor cycle drive by, the sound of the motor changes from a higher pitch to a lower pitch as a result of...

the law of conservation of energy.

a change in speed of the light.

When an airplane is flying above, you hear the sound of the plane further back than where the plane actually is in the air. Why is this?

The speed of the plane is faster than the speed of the sound.

The frequency of the plane is higher than the frequency of the sound.

The frequency of the sound is higher than the frequency of the plane.

The speed of the sound is faster than the speed of the plane.

Which wave in the picture has the quietest sound?

They have the same amplitude so they are the same volume

How is the frequency of the sound waves in front of the moving source different from the frequency of the sound waves behind the moving source.

The frequency is higher in front of the source than behind

The frequency is lower in front of the source than behind

The frequency is the same in front as it is behind

Impossible to tell without measuring
