Refraction of Light at Plane Surfaces

This topic explains the refraction phenomenon, when a ray of light passes from one optical medium to another medium and deviates. Snell’s Law of Refraction states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant.

In this topic, we will learn the laws of refraction and the concept of refractive index. We will learn about the refractive index of different materials. It also highlights the properties of refraction of light and application of refraction.

The topic discusses light refraction on a rectangular glass block in experimental way. We will also learn about emergent ray, incident angle and lateral displacement. It also explains the phenomenon of refraction through glass.

A prism is a transparent material bounded by two triangular and three rectangular lateral surfaces. The rectangular surfaces are inclined to each other. The shape of a prism makes the refracted ray deviate from the direction of the incident ray.

In this topic, we will learn about the light refraction and its impact on image formation. It explains how the refraction of light through an object can alter the view of that object. We will also learn about how image formation works.

This topic deals with the concept of total internal reflection and critical angle. Total internal reflection in nature and its technological applications are also explained here.
