Question

how will you get the light of different wavelength and frequency from a given source of light ?​

Answer 1

Answer:

Laser lights emit light in one wavelength, that is, only in one colour. This property of laser lights is called MONOCHROMATICITY.

Ordinary lights emit light in many wavelengths, that is, in many different colours. These different colours combine to form a mixture that a s a result appears as white.

This a point of difference between laser lights and ordinary lights

Answer 2

Answer:

Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies. In the visual system, a light wave's wavelength is generally associated with color, and its amplitude is associated with brightness.
