In a modified YDSE, the region between the screen and slits is immersed in a liquid whose refractive index varies with time as `mu_(1) = (5 // 2) - (T // 4)` until it reaches s steady state value of `5 // 4`. A glass plate of thickness 36 `mu m` and refractive index `3//2` is introduced in front of one of the slits.

What is the speed of the central maxima when it is at

In a modified YDSE, the region between the screen and slits is immersed in a liquid whose refractive index varies with time as mu_(1) = (5 // 2) - (T // 4) until it reaches s steady state value of 5 // 4 . A glass plate of thickness 36 mu m and refractive index 3//2 is introduced in front of one of the slits. Find the time when central maxima is at point O. located symmetrically on the x-asix.

In YDSE when slab of thickness t and refractive index mu is placed in front of one slit then central maxima shifts by one fringe width. Find out t in terms of lambda and mu .

Explain what happens when a convex lens of refractive index 1.2 is immersed in a liquid of refractive index 1.3 .

Explain what happens when a convex lens of refractive index 1.2 is immersed in a liquid of refractive index 1.3 .

In Young's double-slit experiment, let A and B be the two slit. A thin film of thickness t and refractive index mu is placed in front of A. Let beta = fringe width. Then the central maxima will shift

A YDSE is conducted in water (mu_(1)) as shown in figure. A glass plate of thickness t and refractive index mu_(2) is placed in the path of S_(2) . The optical path difference at O is
