There's no difference

a higher pitch than if he were standing still

a lower pitch than if he were standing still

the same pitch he would if he were standing still

a higher pitch than if she were standing still

a lower pitch than if she were standing still

the same pitch he would if she were standing still

lower pitched than they would normally.

higher pitched than they would normally.

the same pitch they would normally.

It decreases

It turns red

the wavelength gets longer

The wavelength gets shorter

the wavelength doesn't change

I have no idea

Frequency higher than 600 Hz

Frequency lower than 600 Hz

Exactly 600 Hz

No sound, silence.

An apparent change in the frequency of sound or other waves because of motion of the source or observer.

The change in the actual vibration creating the wave as an object travels faster.

The change in the actual vibration creating the wave as an object travels slower.

A change in pitch that causes frequency of sound or other waves to disappear
