The Doppler effect can help us identify periodic motion. That's exactly how
we know about many double stars orbiting each other, even when we can't
separate their images in a telescope.
As one of the stars moves in its orbit first toward us, then away from us, then
toward us again, we see its spectrum blue shift, then red shift, then blue shift
again, with a period of days, weeks, months, or even years.

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
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.
Would it be correct to say that the Doppler effect is the apparent change in speed of a wave due to motion of the source?
No, the doppler effect applies to changes in frequency.
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.

Would it be correct to say that the Doppler effect is the apparent change in the speed of a wave due to the motion of the source?
No. The Doppler effect is about a change of frequency, not about a change of speed. The relative speed may change as well, but that's not what the Doppler effect is about.
What do you call the change in sound frequency due to a relative motion?
The Doppler Effect.
Doppler effect states that the motion of any object can?
Shift the wavelength of the spectrum.
Does the wave speed change in the Doppler effect?
Yes, the Doppler effect defines the change in speed of a sound wave due to motion. As I recall, the Doppler Effect is a change in the frequency of a wave, not its speed. Yep, I'm pretty sure Doppler is a frequency change, not a speed of sound change.
