Question

what is interference of light

Answer 1

something that interferes. 3. Physics. the process in which two or more light, sound, or electromagnetic waves of the same frequency combine to reinforce or cancel each other, the amplitude of the resulting wave being equal to the sum of the amplitudes of the combining waves.

Answer 2

When two light waves superpose with each other in such away than the crest of one wave falls on the crest of second wave, and tough of one wave falls on the tough of the second wave, than Resultant wave has larger amplitude and it is called Interference of light
