An interference pattern was made by using red light. If the red light changes with blue light, the fringes will become

Assertion (A) : Interference pattern is made by using blue light instead of red light, the fringes becomes narrower. Reason (R ) : In Young's double slit experiment, fringe width is given by the relation beta = (lambda D)/(d)

In the interference pattern all the fringes are of equal emit light of

A single slit diffraction pattern is obtained using a beam of red light. If the red light is replaced by the blue light, then the diffraction pattern

Red light differs from blue light in its

Red light differs from blue light as they have :
