Explanation:
direction of light changes as it passes from one medium to another. In other words, light bends as it travels from one medium to another. This phenomenon is known as refraction.
When light waves travel from one optical medium to another, they get refracted due to difference in optical density of the two media.
The degree of refraction varies with the wavelength of light.
The speed of light in different media varies inversely with the refractive index of a medium
Angle of Prism: A glass prism has two triangular bases and three rectangular lateral surfaces that are inclined at an angle, called the angle of the prism.
A glass prism PQR has been kept on its base QR. A ray of light AB is incident on the faces PQ of the prism. Here AB is an incident ray.
When a ray of light passes through a prism, it bends towards the base of the prism: The incident ray AB is incident is going from air(rare medium) into glass (denser medium), so it bends towards the normal BN’ and goes along the direction BC inside the glass prism. Thus BC is the refracted ray of light which bends towards the base QR of the prism.
When the ray of light BC travelling in the glass prism comes out into air at point C, refraction takes place again.
Since the ray BC is going from the glass (denser medium) into air(rarer medium), the ray bends away from the normal MC and goes along the direction CD in the form of emergent ray.
