A small transparent slab containing material of `mu=1.5` is placed along `AS_(2)`(figure). What will be the distance from O of the principle maxima and of the first minima on either side of the principal maxima obtained in the absence of the glass slab ?

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?
