The Doppler effect of a passing siren results from an apparent change in?
the frequency of the wavelength
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.
What is A change in the observed wavelength or frequency of a wave that occurs when the source of the wave or the observer is moving?
Doppler Effect :)
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
What is a dopper 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.

What is an explanation of the Doppler shift?
The Doppler Shift is a change in frequency due to the Doppler Effect.
Does wavelenght change in Doppler effect?
yes, because as the source comes closer to the observer or vice versa the observer's frequency will be greater than the sourcer's frequency thus the wavelength will be less and vice versa.
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 Doppler Shift as it applies to light?
That's more or less the same as the Doppler shift for other waves: a change of frequency, caused by relative movement between the source and the observer. When the distance is increasing the wavelength of the light increases. When the source of light and the observer are getting closer, the light's wavelength decreases. Red light has a longer wavelength than blue light.
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.
The change in frequency of sound waves in the Doppler effect is hear as a change in what?
A change in pitch.
How the wavelength traveling with the same speed would change if the frequency of the waves increase?
The speed of a wave is equal to the wavelength divided by the frequency (speed = wavelength/frequency). So if the frequency of the wave increases, the wavelength will decrease.
