In a double slit experiment a parallel beam of light strikes the slit plane at an angle theta as shown in the figure. The two slits are covered with transparent plastic sheets of equal thickness t but of different refractive indices 1.2 and 1.5. The central maxima is formed at the centre of the screen at C. (a) Which sheet was used to cover the slit S1? (b) Find theta .

A monochromatic beam of light of 6000 Å is used in YDSE set-up. The two slits are covered with two thin films of equal thickness t but of different refractive indices as shown in figure. Considering the intensity of the incident beam on the slits to be I_(0) , find the point on the screen at which intensity is I_(0) and is just above the central maxima. (Assume that there is no change in intensity of the light after passing through the films.) Consider t = 6 mu m, d = 1 mm, and D = 1 m, where d and D have their usual meaning. Give your answer in mm.
