Refraction of Light

Velocity of light is greater in denser medium than in rarer medium.

If the light is incident at right angles then it will pass through the glass slab without any deviation.

Through a glass slab, the light before coming back to the air suffers refraction two times.

The refraction happening in a glass slab and prism are the same.

Explain the process of refraction happening in a glass slab.

Explain the process of refraction happening in a rectangular prism.

The ray coming out of a glass after refraction is known as the emergent ray.

In an experiment to trace the path of ray through a glass slab, Shiva traced as shown in the figure. Out of AB, BC and CD, _____ is the emergent ray.

A thin prism P₁ with angle $4^{\mathrm{o}}$ and made from glass of refractive index $1.54$ is combined with another thin prism P₂ made from glass of refractive index $1.72$ to produce dispersion without deviation. What is the angle of prism in degree ?

Calculate refractive index of a equilateral glass prism for a light of red colour. Angle of minimum deviation for red colour is $30°$.

A ray of light incident at an angle of $48°$ on a prism of refracting angle $60°$ suffers minimum deviation. Determine the angle of minimum deviation in degrees.

The angle of _____ increases with the increase in the angle of prism.

The angle of deviation depends on the refractive index of the glass.

For a given prism, the _____ light deviates most and the red light deviates least.

A ray of light while travelling from medium A to B, deviates away from the normal. The speed of light in:

A ray of light passes through an equilateral glass prism in such a manner that the angle of incidence is equal to the angle of emergence and each of these angles is equal to ${\frac{3}{4}}^{\mathrm{th}}$ of the angle of the prism. The angle of deviation is 

Refraction is the phenomenon of bending of the ray of light when it passes from one medium to the another with different optical density.

A laser beam enters from air to soap solution in water then _____.

Observe the given figure and answer the following question:

Name the process represented by the figure.

(Choose from Refraction/ Reflection)

A ray is incident at an angle of incidence on one surface of a prism at small angle $A$ and comes out normally from the opposite surface. Hence, the angle of emergence is _____ degree.
