Question

There are two sources kept at distances 2 . A large screen is perpendicular to line joining the sources. Number of maximas on the screen in this case is ( = wavelength of light).

Answer 1

Answer:

ExΔxmax = 0 and Δ xmax = 2λ

Theortical maximas are = 2n + 1 = 2 × 2 + 1 = 5

But on the screen there will be three maximasplanation
