In a Young's double slit experiment, the light sources is at distance l_1 = 20mu m and l_2 = 40 mu m form the main slit. The light of wavelength lambda = 500nm is incident on slits separated at a distance 10mu m . A screen is placed at a distance D = 2 away from the slits as shown in figure. Find (a) the values of theta relative to the central line where maxima appear on the screen? (b) how many maxima will appear on the screen? what should be the minimum thickness of a slab of refractive index 1.5 placed on the path of one of the ray so that minima occurs at C ? .
