Question
Write characteristics of Laser rays.

Answer

Characteristics of Laser rays :
(i) These are highly coherent rays.
(ii) These are unidirectional.
(iii) Intensity and power of these rays are very much.
(iv) The main characteristic of these rays is that these rays spread very less on conversing a long distance.
(v) Band width of laser rays is very less.
(vi) The rays can be superimposed with other rays of different wavelength to form waves of new light waves.
(vii) These rays can be changed from one colour into another.
(viii) These rays are monochromatic.
