Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself? Explain using a diagram.

Why is there no dispersion of light refracted through a rectangular glass slab ? Give reason.

A ray of light ,incident on an equilateral glass prism (mu_g=sqrt3) moves parallel to the base line of the prism inside it.Find the angle of incidence for thsi ray.

A beam of light composed of red and greeen ray is incident obliquely at a point on the face of rectangular glass slab.When coming out on the opposite parallel face,the red and green ray emerge from

A ray of light is incident at the glass-water interface at an angle i. It merges finally parallel to the surface of the water. Then, the value of mu_g would be(where mu_g is the refractive index of glass with respect to water)

Consider a light beam incident from air to a glass slab at Brewster's angle as shown in Fig. EP 10.1. A polarised is placed in the path of the emergent ray at point P and rotated about an axis passing through the center and perpendicular to the plane of the polaroid.

Discuss refraction through a glass slab and show that emergent ray is parallel to incident ray but displaced?

A ray of light is incident at an angle of 60^@ on one face of a rectangular glass slab of thichness 0.1 m and refractive index 1.5.Calculate the lateral shift produced.
