A thin paper of thickness 0.02 mm having a refractive index 1.45 is pasted across one of the slits in a YDSE. The paper transmits 4/9 of the light energy falling on it. (a) Find the ratio of maximum intensity

White coherent light (4000-7000 A) is sent through the slits of a YDSE. The separation between the slits is 0.5 mm and screen is 50 cm away from the slits. There is a hole in the screen
