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.

There is a Young's double-slit experiment set-up completely dipped in water. Assume that the refractive index of water is mu_1 . One of the slits is covered with a thin film of thickness t and refractive index mu_2 . What will be the optical path difference at the centre of screen ?

YDSE is carried with two thin sheets of thickness 10.4 mu m each and refractive index mu_1 = 1.52 and mu_2 = 1.40 covering the slits S_1 and S_2 respectively. If white light of range 400nm to 780 nm is used, then which wavelength will form maxima exactly at point O, the centre of the screen

In Young’s double slit experiment a transparent sheet of thickness t and refractive index mu is placed in front of one of the slits and the central fringe moves away from the central line. It was found that when temperature was raised by Deltatheta the central fringe was back on the central line (at C). It is known that temperature coefficient of linear expan- sion of the material of the transparent sheet is alpha . A young scientist modeled that the refractive index of the material changes with temperature as Deltamu"= – gama Deltatheta . Find Deltatheta in terms of other given quantities. D and d are given and have usual meaning.
