What else can I help you with?
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.
What happens to sound waves when the source of a sound is moving toward you?
When the source of a sound is moving toward you, the sound waves emitted by the source are compressed, resulting in a higher frequency of the sound you hear. This phenomenon is known as the Doppler effect and is commonly experienced with sirens from emergency vehicles approaching you.
What happens if a source is moving toward you at a high rate of speed?
If a source is moving toward you at a high rate of speed, you would perceive an increase in its frequency, resulting in a higher pitch (Doppler effect). This is commonly experienced with emergency vehicles approaching with sirens on.
Which refers to the change in wavelength tht occurs when an object moves toward or away from a source?
Doppler effect refers to the change in wavelength that occurs when an object moves toward or away from a source.
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?
The phenomenon is called the Doppler effect. It describes the change in frequency of waves when the source of the waves is moving relative to the observer. In police radar, this effect is used to measure the speed of vehicles by detecting the frequency shift of the waves reflected off the moving vehicle.

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.
An apparent shift in the wavelength of light emmited by a light source moving toward or away from an observer is known as?
Doppler effect. It results in a change in the observed frequency of the light as the source moves relative to the observer. This effect is commonly seen in everyday scenarios, such as the change in pitch of a siren of a moving vehicle.

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 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.
Which refers to the change in wavelength tht occurs when an object moves toward or away from a source?
Doppler effect refers to the change in wavelength that occurs when an object moves toward or away from a source.

In police radar, this effect is used to measure the speed of vehicles by detecting the frequency shift of the waves reflected off the moving vehicle.
How does perceived pitch change as a sound passes a listener?
The perceived pitch of a sound can change as it passes a listener due to the Doppler effect. If the sound source is moving toward the listener, the pitch will be higher; if the source is moving away, the pitch will be lower. This is because of the compression or expansion of sound waves as the source moves relative to the listener.
Whenever a source of sound moves the frequency heard by the observer is Less than that of the source?
To be more specific, a sound source moving toward you will appear to emit a sound of higher frequency than actual. Conversely, a sound source moving away from you will appear to emit a sound of lower frequency than actual. See "the Doppler effect."
For a stationary observer when the source of a sound is moving it's pitch appears to change?
Yes, that's correct. When a sound source is moving toward an observer, the pitch appears higher (frequency increases) due to compression of sound waves, and when moving away, the pitch appears lower (frequency decreases) due to stretching of sound waves. This effect is known as the Doppler effect.
