Refraction Theory |Numericals and Reflection by Glass Slab

What is meant by refraction of light ? State the laws of refraction. Show that emergent ray from a glass slab is parallel to incident ray.

Laws OF Refraction||Refraction on plane Surfaces||Shift by a glass slab

A light ray falls on a rectangular glass slab as shown. The index of refraction of the glass, if total internal reflection is to occur at the vertical face, is

Introduction||Huygens Wave theory||Derivation OF Reflection & Refraction using Huygens Theory

A concave mirror of focal length 2 cm is placed on a glass slab as shown in the figure. The image of point object O formed due to reflection at mirror and then refraction by the slab

A ray of light in air is incident on a glass slab at an angle of incidence of 60^(@) . When it travels through glass, it is deviated through 15^(@) . What is the refractive index of the material of the glass slab ?

In an experiment with a rectangular glass slab, for an angle of incidence of 60^@ in air, angle of refraction is measured to be r_1 . When the glass slab is replaced by a hollow slab filled with water, angle of refraction is measured to be r_2 . Show that r_2 gt r_1 . Justify your answer.

A ray of light of internsity I is incident on a parallel glass slab at a point A as shown. It undergoes partial reflection and refraction. At each reflection and refraction. At each rerflection 20% of incident energy is reflectrd. The rasys AB and A' B' undergo interference. The ratio I_(max)//I_(min) is

Statement I: A lighr ray is incident on a glass slab. Some portion of it is reflected and some is refracted. Reeefracted and reflected rays are always perpendicular to each other. Statement II: Angle of incidence is equal to angle of reflection.
