Application +4 | -1

Two coherent sources each emitting light of Intensity

I_0

interfere in a medium at a point where phase difference between them is

\frac{2 \pi}{3}

. The resultant intensity at the point is

View answer and explanation

Correct option: A

I_o

Option A (

I_o

) is correct because the resultant intensity is calculated using the formula

I = 4I_0 \cos^2(\frac{\phi}{2})

with

\phi = \frac{2\pi}{3}

.
