If you are moving toward the source of a sound wave and then pass the source and continue moving away the will change.?

The pitch becomes lower because the sound waves are no longer compressed once the source passes you.

∙ 7y agoThe frequency of the wave will change, in that case, as a result of the Doppler effect.

What lets you know that the source of a sound is moving toward or away from you?
When a sound-source moves toward you, its pitch gets higher and the sound gets louder. When it moves away, the pitch lowers and it gets quieter. The frequency change is called the Doppler shift.
Can you change the frequency of em wave?
Once the wave has left the source that generated it, the frequency can't be changed.If you happen to be moving toward or away from the source at a high enoughspeed, then the frequency of the radiation may appear to you to be changed.But it's not.
When you are moving toward a stationary source of a sound its frequency will appear lower than it actually?
False
What phenomenon is the basis of police radar and makes light or sound waves increase in frequency if the source is moving toward the observer and decrease if the source is moving away?
Its called the doppler effect.
What causes the frequency of light from a moving object to change?
It is the Doppler effect that causes the apparent shift in the frequency of light or sound waves as the source and observer are moving farther apart or closer toward each other. Use the link below for more information.

An amoeba moving toward a food source is what?
Using a microscope, you observe an amoeba moving toward a food source. This is an example of responsiveness. Endocytosis produces a structure called a food vesicle.
What happens if the source of a sound is toward you at a high rate of speed?
If the source of a sound is moving towards you, then the pitch of the soundyou hear is higher than the pitch of sound that the source is actually emitting.The rate of speed doesn't matter.BTW ... this also happens if you are moving toward the source.

Its called the doppler effect.
What are the four types in Doppler effect?
Frequency change when 1)Source moves toward the observer 2)Source moves away from the observer 3)Observer moves toward sourse 4)Observer move away from the sourse, otherthan these observer and sourse moving away or towards each other.

An apparent shift in the wavelength of light emmited by a light source moving toward or away from an observer is known as?
The Doppler Effect.
What happens if a source of sound is moving toward you at a high rate of speed?
The waves compress which causes a lower tonal quality.
When a wave source is moving toward or away from an object the wavelength changes a phenomenon known as the?
The Doppler Effect See related link
Which refers to the change in wavelength tht occurs when an object moves toward or away from a source?
doppler effect
