Q1. What is refractive index? Ans: Refractive index is defined as the ratio between the sine of the angle of incident ray i in a vacuum to the sine of the angle of refraction r in a given medium. The mathematical representation of the refractive index is given as:

In circular polarization the electric vector rotates about the direction of propagation as the wave progresses. Light may be polarized by reflection or by passing it through filters, such as certain crystals, that transmit vibration in one plane but not in others.

Q6. What happens to the incident ray when it enters the prism? Ans: When an incident ray enters the prism, it bends towards the normal as it changes its path and gets deviated.

…are asymmetrical, the use of circular polarization can enhance the detection of aircraft in rain. With circular polarization, the electric field rotates at the radar frequency. Because of this, the electromagnetic energy reflected by the rain and the aircraft will be affected differently, which thereby makes it easier to distinguish…

Q5. List the factors on which the angle of deviation through a prism depends. Ans: Following are the factors on which the angle of deviation through a prism depends:

Polarization

A prism is defined as a polyhedron with a triangular base and three rectangular lateral surfaces. It is used as an optical object to study the behaviour of white light when it is passed through it. The light bends at various angles like an angle of incidence, angle of reflection, angle of refraction, and angle of deviation.

A prism is a transparent optical object with two flat surfaces that have an angle between them. When the light enters the prism, there is a bending of light as there is a change in the speed of light. The bending of the light is dependent on the angle of incidence, normal, and refractive indices. There are four different types of angles involved in this experiment, and they are the angle of incidence, angle of emergence, angle of prism and angle of deviation. Below is an experiment to trace the path of a light ray through a glass prism.

Linear polarization

20141014 — Unpolarized light, in general, consists of polarized components in all directions perpendicular to the direction of propagation of the wave.

Elliptical polarization

Q2. What is the unit of the refractive index? Ans: Refractive index has no unit. This is because it is a ratio between the speed of light in vacuum and in a medium.
