Two monochromatic coherent light beams A and B have intensities

I

and

\frac{I}{4}

respectively. If these waves are superposed, the maximum and minimum intensities will be

View answer and explanation

Correct option: A

\frac{{9I}}{4},\frac{I}{4}

Option A (

\frac{{9I}}{4},\frac{I}{4}

) is correct because the maximum intensity is proportional to the square of the sum of the amplitudes, and the minimum intensity is proportional to the square of the difference of the amplitudes.
