What is monochromatic source?
A monochromatic source is a source of light of a discrete wavelength. White light is a mixture photons with wavlengths from 390 to 750 nm (what the human eye can detect). The monochrmatic light will have a specific wavelength. For example all photons have wavelength 200 nm.
What covers the light of a microscope to shorten the wavelength?
A blue filter only allows shorter wavelengths of light to pass. So, covering the light source of a light microscope with a blue filter shortens the wavelength of light passing through the objective.
How does the frequency of radiant energy relate to the absolute temperature of the radiating source?
A low temp source emits low-frequency, long wavelength waves. A medium temp source emits medium frequency, medium wavelength waves. A high temp source emits high frequency, short wavelength waves.
In the Doppler effect for sound if the source and receiver are at rest but the air is moving will there be any change in frequency or wavelength?
No change in frequency or wavelength.
Energy is defined as the capability to perform work or?
energy is defined as the ability to do....work.
What source of heat does a halogen light use?
an electric current passed through it
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.

Which light you will see if violet light is passed through a red filter?
none if the source is purely violet and the filter is 100% red.
How the ozone pollutant level is measured?
An air sample is pulled through a calibrated size chamber, and UV of wavelength 254 nm is passed through that gas stream. The intensity of the light source is periodically calibrated, and the intensity received across the chamber is measured. The "Beer Lambert law" is used to infer the amount of ozone present in the chamber, and the "pollution level" is then known. Other methods are being researched.
What change has occurred to the speed and wavelength of the light to cause the redshift?
We know that the frequency of light doesn't change once it leaves the source, and we know that as long as light stays in the same medium, its speed doesn't change. So if the color of visible light traveling through the vacuum of space has shifted toward the red end of the spectrum, then its wavelength has become longer since it left the source.
What are primary sources and secondary sources in relation to history?
A primary source is a source that has come directly from a person in those times who witnessed what was going on and a secondary source is a source that has been passed down through the years so it could of been twisted or something like that.

Which adjustment might cause an electric current to flow?
Switch to a light source with a shorter wavelength.... Switch to a light source with a higher frequency
