Question 11 (Choice 2) (a) If the slits in Young's double slit experiment are identical, then intensity at any point on the screen may vary between zero and four times to the intensity due to single slit". Justify the above statement through a relevant mathematical expression. The total intensity at point where the point where the phase difference is βˆ…, is given by 𝐼 = 𝐼_1+𝐼_2+2√(𝐼_1 𝐼_2 ) cos⁑"βˆ…" . Here 𝐼_1 and 𝐼_2 are the intensities of two individual sources which are equal. When βˆ… is 0, 𝐼=γ€–4𝐼〗_1 When βˆ… is 90Β°, 𝐼=0 Thus intensity on the screen varies between γ€–4𝐼〗_1 and 0.
