Two light waves of same intensity on superposition gives a maximum of 400 units. If amplitude of both waves are reduced by

50 \%

then the maximum intensity will be-

View answer and explanation

Correct option: C

100

Option C (100) is correct because the maximum intensity is proportional to the square of the amplitude, and reducing the amplitude by 50% reduces the intensity to 1/4 of the original.
