Optical Path||YDSE with Transparent Slab

YDSE 2

YDSE-1

In YDSE, the sources is place symmetrical to the slits. If a transparent slab is placed in front of the upper slit, then

Optical Path Length In Ydse

A ray of light travels through a transparent slab with a speed of 2 xx 10^(10) cms^(-1) . This implies that therefractive index of the slab material is

Geometrical Optical Path |Displacement Of Fringes|Questions

When light rays are incident on a thick transparent slab then these rays are partly reflected and partly refracted into the slab. At a certain angle of incidence theta , it is found that reflected and refracted rays are mutually perpendicular. What is refractive index of material ?
