What else can I help you with?
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.
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 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.
When the source of sound is moving its speed increases true or false?
False. The speed of sound in air is constant, around 343 meters per second. When the source of sound is moving, it can affect the frequency and intensity of the sound, but not the speed at which the sound travels.
Does speed increase for an observer that stays in one spot when the source of a sound is moving?
No, the speed of sound is constant in a medium, so the speed of sound heard by an observer staying in one spot does not change if the source of the sound is moving. The frequency and wavelength of the sound may be affected by the motion of the source, but not the speed.
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.

When the source of a sound is moving its speed incress?
When the source of a sound is moving, the speed of sound waves emitted from the source is not affected by the motion of the source itself. However, the perceived frequency of the sound may change due to the Doppler effect, if the source is moving towards or away from the listener.
What happens to the speed of moving abject when it is pushed in the direction of motion?
its speed increases
When the source of a sound is moving its speed increases.?
B. False
If a light source is approaching you at a speed very close to the speed of light it will appear?
All of the frequencies emitted by the source would appear higher to me, all of the wavelengths would appear shorter, and anything that was visible to me would appear shifted toward the blue end of the spectrum, compared to what it was when it left the source. If, as you say, the source is approaching me at nearly the speed of light, then the 'shift' will be extreme. What left the source as radio waves might be visible to me, and what left the source as visible light might appear to me as hard X-rays or even gamma rays. By the way ... one thing that must be mentioned and appreciated is the fact that even if the source is approaching me at nearly the speed of light, if I measure the speed of the radiation from it as it sails past me, I'll see the radio, visible, X-ray, whatever ... moving past me at the speed of light ... 300,000 kilometers per second. Doesn't matter if the source is moving toward me, away from me, slow, fast, or sideways.
Is the Doppler effect noticeable when in motion of the source is at a right angle?
Assuming the source is moving in a straight line, there will always be a line between you and the source's path that meets the path at 90 degrees, unless you are directly in the path of the source or directly behind it. The important factor is the speed of the approach toward you, and then away from you.
What is the color of the shift in the laser light if a helicopter is moving toward you at its fastest speed?
If a helicopter is moving toward you at its fastest speed, the color shift in the laser light would be towards the blue end of the spectrum. This is known as a "blueshift" and occurs when the source of light is moving towards the observer, causing the light waves to be compressed and appear more blue.
