Would there be a Doppler effect if the source of sound were stationary and the listener in motion?

Yes. The observer would still receive less - or more - wave crests per second.

What is the change in frequency of a sound due to motion of the source?
The change in frequency is caused by the Doppler Effect
A detected apparent change in the pitch caused by the motion of a sound source or of an observer is called?
The Doppler effect.The Doppler effect.The Doppler effect.The Doppler effect.
The blank effect allows us to use the spectrum to study a source's motion?
The Doppler affect
Does the Doppler effect happen with light?
Yes, the Doppler effect can be applied to light. Any wave function can be subject to the Doppler effect if there is relative motion between the source and an observer. That's how we know that the Universe is expanding.
Would it be correct to say that the Doppler effect is the apparent change in the speed of a wave due to motion of the source?
No, the doppler effect applies to changes in frequency.

How Doppler effect?
The apparent change in the frequency due to motion of the source relative to the listener or vice versa is called Doppler's effect . Uses of Doppler's effect : It is used to compute the velocities of stars relative to earth by noting change in wavelength. It is also used to detect moving objects like aircraft by reflect of the radar waves.
What is the definition of Doppler?
An Austrian physicist, Christian Doppler, is best known for the effect named after him, the Doppler effect, which he proposed in 1842. It is the change in frequency of a wave as measured by an observer in motion relative to the source of the wave.The Doppler effect (or Doppler shift) is the change in frequency and wavelength of a wave for an observer moving relative to the source of the waves. It is commonly heard when a vehicle sounding a siren approaches, passes and recedes from an observer. The received frequency is increased (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is decreased during the receding motion. The higher or lower frequency alters the pitch of the sound as heard by a stationary listener, making it sound higher-pitched or lower-pitched.
What is an apparent change in frequency of a sound source that moves relative to an observer?
The Doppler Effect. It's a change in frequency cause by the motion of the sound source, the motion of the listener, or both. As a source of sound approaches, observers hear a higher frequency. When the sound source moves away, observers hear a lower frequency. This effect was discovered by an Austrian scientist named Christian Doppler. Example: An ambulance siren. As the ambulance approaches a stationary observer, the frequency seems to increase. As the ambulance moves farther away, the loudness of the siren seems to decrease.

Does an ambulance siren's pitch really change - what if the ambulance was stationary?
Modern electronic sirens change amplitude and pitch. Older sirens produced tones that changed in amplitude (volume) but were changed in pitch by their motion relative to the listener: increasing in frequency as they approached and decreasing in frequency when they moved away. This is called the Doppler Effect.

For the Doppler effect to occur?
For the Doppler effect to occur the measured object must be in motion (radial velocity) relative to the emitter of a wave.
Does the Doppler effect happen with light?
Yes, the Doppler effect can be applied to light. Any wave function can be subject to the Doppler effect if there is relative motion between the source and an observer. That's how we know that the Universe is expanding.
