Two identical radiators have a separation of d=λ/4 where λ is the wavelength of the waves emitted by either source. The initial phase difference between the sources is λ/4. Then the intensity on the screen at a distant point situated at an angle θ=30∘ from the radiators is (here I0 is intensity at that point due to one radiator alone)
