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.
no. frequency and wavelength are the only things that change
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.
No. Doppler effect measures relative speed toward or away from the observer, there is no effect on the star itself.
No, the doppler effect applies to changes in frequency.
No. The Doppler effect is an apparent change in frequency, due to movement, away from towards the observer.

The Doppler effect is the change in frequency of a sound wave. The Doppler effect causes a siren or engine to have a higher pitch when it is approaching than it does when it is receding.
The Doppler Effect is the change of frequency of a wave that is getting closer to a source. It was named after Christian Doppler who was an Austrian physicist.
No. The Doppler effect is an apparent change in frequency, due to movement, away from towards the observer.
Doppler Effect
The Doppler effect is the change in frequency or wavelength of a wave for an observer who is moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842.
Doppler Effect :)
Sound is a wave; the sound wave is distorted by the Doppler effect. You can clearly hear the change in pitch, from the point where the car approaches you, to the point where it moves away from you.
That's called the "Doppler effect".
