Intensity of central maxima in Young’s double slit experiment is found to be 20 units. Then intensity at a point where phase difference between identical interfering waves is

\frac{\pi }{2}

View answer and explanation

Correct option: A

10 unit

Option A (10 unit) is correct because the intensity is calculated using the formula

I = I_{max} \cos^2(\frac{\phi}{2})

with the given phase difference.
