i want to know the relationship between wavelenght,illumination?

Question

consider a longer wavelength say red, and a shorter wavelength say blue or green.

Answer 1

As previously stated, wavelength is directly related to frequency and therefore the part of the spectrum you are addressing. There is no relationship between wavelength and intensity per se.

That being said, however, there is a certian apparent relationship in that the human eye has evolved under a the light of a yellow dwarf star and so our eyes are attuned to detect the visible spectrum more accutely than other parts of the sectrum. So we do not perceive colors beyond violet or red as well as we do green or yellow or blue.
Some wavelengths, such as infared or ultraviolet are invisible to us, so even though they may be broadcast with the same intensity, our eyes simply are less sensitive to them.

Answer 2

Mostly my dear wavelength is related with frequency not illumination......

The shorter the wavelength the higher the frequency.

Illumination does not affect the wavelength as it only increases the intensity of brightness not the wavelength since the wavelength is fixed for each type of radiation or light..............

Answer 3

spare ourselves... go get a copy of University Physics!
