Light of wavelength 6 xx10^(-5) cm falls on screen at a distance of 100 cm from a narrow slit. Find the width of the slit if the first minima lies 1mm on either side of the central maximum

A point object O is placed at a distance of 41 cm from a convex lens of focal length f = 20 cm on its principal axis. A glass slab of thickness 3 cm and refractive index mu = 1.5 is placed between the lens and the object with its faces perpendicular to the principal axis of the lens. Image of the object is formed at point I_(1) . Now the glass slab is tilted by an angle of theta = 1° (as shown in the Figure) and the final image is formed at I_(2) . Calculate the distance between points I_(1) and I_(2) . Consider only paraxial rays for the lens and near normal incidence for the glass slab.

Light of wavelength lambda = 500 nm falls on two narrow slits placed a distance d = 50 xx 10^-4 cm apart, at an angle phi= 30^@ relative to the slits as shown in figure. On the lower slit a transparent slab of thickness 0.1 mm and refractive index 3/2 is placed. The interference pattern is observed at a distance D=2m from the slits. Then, calculate (a) position of the central maxima. (b) the order of maxima at point C of screen . (c)how many fringes will pass C, if we remove the transparent slab from the lower slit?

In YDSE arrangement as shown in figure, fringes are seen on screen using monochromatic source S having wavelength 3000 Å (in air). S_1 and S_2 are two slits seperated by d = 1 mm and D = 1m. Left of slits S_1 and S_2 medium of refractive index n_1 = 2 is present and to the right of S_1 and S_2 medium of n_2 = 3/2 , is present. A thin slab of thickness 't' is placed in front of S_1 . The refractive index of n_3 of the slab varies with distance from it's starting face as shown in figure. In order to get central maxima at the centre of screen, the thickness of slab required is :
