{S_1}\;and\;{S_2}

are two coherent sources. The intensity of both sources are same. If the intensity at the point of maxima is

\mathrm{4}\;\mathrm{W}{\mathrm{m}^{ - 2}}

, the intensity of each source is

View answer and explanation

Correct option: A

\mathrm{1}\;\mathrm{W}{\mathrm{m}^{ - 2}}

Option A (

\mathrm{1}\;\mathrm{W}{\mathrm{m}^{ - 2}}

) is correct because the maximum intensity is four times the intensity of each individual source when they are coherent and have the same intensity.
