What is the Doppler effect on sound?
The Doppler effect is a phenomenon observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for the observer and the source are approaching and an apparent downward shift in frequency when the observer and the source is receding. The Doppler effect can be observed to occur with all types of waves - most notably water waves, sound waves, and light waves.
Which color has a higher frequency?
In the visible-light portion of the electromagnetic spectrum, frequencies are lowest near red light (approaching infrared waves) and highest near violet light (approaching ultraviolet rays).
When light waves are emitted by a moving source scientists can measure?
When light waves are emitted by moving source scientists can measure the Doppler effects. It is a source of energy that produces light.
What waves have the most light waves?
Light wave is an electromagnetic wave, so light waves are a kind of wave. I don't understand what you mean by what waves have the most light waves. It's not possible to emit a combination of different kinds of waves (such mechanical, EM wave, sound wave) from a single source.
What are light waves that moves together as they travel away from their source?
coherent

What type of wavefront will emerge from a point source and distant light source?
For a point in space (or from a distant light object), spherical waves are emitted. From a point source on the surface of a liquid, circular waves will come out. In both cases the source will be the focus of the emitted waves.
If a source of sound waves is rapidly approaching a person the sound heard by the person appears to have?
a frequency higher then the original frequency...
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.
Are infrared waves source of heat or ultra violet?
What is the source of the infrared light wave?

Light and sound waves have many similar properties however light waves are what while sound waves are what?
Light waves are eletromagnetic waves and sound waves are mechanical waves. Additionally, a light wave is a transverse wave that does not require a medium through which to travel. Sound waves, on the other hand, are longitudinal waves where the source transfers the mechanical energy of the sound wave into the medium so it can travel.
What do light waves travel in as they move away from the source?
They travel in open spaces
Speed of sound is approx 740mph a police car with its siren sounding is approaching you at 80mph at what speed is the sound from the police siren approaching you?
The sound moves through the air at 740 mph, regardless of the speed of the source. The sound ofthe siren passes you at 740 mph.However, since the source is approaching you, more waves pass you each second than leavethe source each second. That's why the pitch of the sound from an approaching source soundshigher than its actual pitch.Also ... since the sound doesn't move away from the source any faster than 740 mph no matterhow fast the source is moving, that's why the pressure of the sound waves piles up in front ofthe source when the speed of the source approaches 740 mph, forming what's popularly calledthe "sound barrier".
