Assertion (A): For best contrast between maxima
and minima in the interference pattern of Young's
double slit experiment, the intensity of light
emerging out of the two slits should equal.
Reason (R): The intensity of interference pattern
is directly proportional to the square of amplitude.

View answer and explanation
Correct option: A
Both (A) and (R) are correct but (R) is not
the correct explanation of (A)
the correct explanation of (A)
Option A (Both (A) and (R) are correct but (R) is not the correct explanation of (A)) is correct because while both statements are true, the reason doesn't explain why equal intensities lead to best contrast.
