What can scientist measure when light rays are emmitted by a moving source?
Scientist measure when light rays are emitted by a moving source the speed of light. Depending on the moving force they can also measure bending light.
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.
What does reflection involve?
Light being emitted from a source and bouncing off an object
What is the difference between a mobile source and a stationary source?
Well, a mobile source is a source that is capable of moving. And a stationary source is a source that stays still or doesn't move (or stationary in other words).
Which source of energy is used in coastal areas?
moving water

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.
What do sound waves travel away from?
The source that emitted the sound wave.
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.
Is the source of earth's magnetism fully understood by scientists?
No, not fully understood but most of the source and system have understood by scientists.
What does reflection involve?
Light being emitted from a source and bouncing off an object
What energy is removed or given off?
Light and heat are emitted from an energy source...
What is blueshift?
A blueshift is a change in the wavelength of light, in which the wavelength is shorter than it was when it was emitted at the source.
What are red shift lines?
when a luminous source is relatively moving away, the light emitted from the source is almost stretched (the frequency of the waves decrease). In other words, enough redshift will cause violet light to become red due to a decrease in frequency. Light which is already red will turn to infra-red, microwaves, and radio waves. If the redshift is very very very high (this does not usually happen in the universe), even x-rays and gamma-rays can be red shifted to radio waves. Similarly, when the source is moving relatively closer, the light emitted will be blue shifted: the frequency will increase. This is called the Doppler shift or the Doppler effect.
Is a candle a light source?
Yes a candle is a light source. Actually, the unit for intensity of light (candela) is based on the light emitted by a candle.
The Doppler Effect is a phenomenon that allows one to measure an object's?
The doppler effect is the change in frequency of a wave for an observer moving relative to the source of the wave. You can measure the location and velocity of a locomotive moving towards or away from your. You can measure a star's location and velocity vector regarding the shift and color emanating from the star light. This is calculated via doppler light equations.
What SI base unit is used to measure light?
The second.I see the "second" as a measure of time, not light.LUX, Lumen or Candela do ring a bell and something like watt per square meter..Yes the S.I. unit measure of light is a limen (lm) .lumen (lm)The SI derived unit for measuring the luminous flux of light being produced by a light source or received by a surface. The luminous intensity of a light source is measured in candela. One lumen represents the total flux of light emitted, equal to the intensity in candela multiplied by the solid angle in steradians (1/(4pi) of a sphere) into which the light is emitted. Thus the total flux of a one-candela light, if the light is emitted uniformly in all directions, is 4pi lumen.
