In Young's double slit experiment, the two slits acts as coherent sources of equal amplitude A and wavelength `lambda`. In another experiment with the same set up the two slits are of equal amplitude A and wavelength `lambda` but are incoherent. The ratio of the intensity of light at the mid-point of the screen in the first case to that in the second case is

In Young's double-slit experiment, the two slits act as coherent sources of equal amplitude A and of wavelength lamda . In another experiment with the same set-up the two slits are sources of equal amplitude A and wavelength lamda , but are incoherent.
