Question

In Young’s double-slit experiment, the two slits act as coherent sources of equal amplitude A and of wavelength λ. In another experiment with the same setup, the two slits are sources of equal amplitude A and wavelengthλ, but are incoherent. The ratio of intensity of light at the mid-point of the screen in the first case to that in the second case is

Solution
