Refraction of Light

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

Refracted ray is the ray of light in the glass slab after the incident ray hits the slab.

Which ray is formed when the light undergoes refraction through a glass slab?

When a ray of light hits a glass slab, it will deviate from its normal path and then _____ ray is formed.

When light passes through a glass slab, the ray of light coming out from the glass slab is known as refracted ray.

Name the angle made between refracted ray and normal when light hits a glass.

Angle of refraction is produced by the rays of light before undergoing refraction.

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

When a light ray hits on a glass surface, it gets refracted. The ray hitting the glass ray is known as 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.

When light fall obliquely on the surface of a thick glass slab, a part of the light reflects at the surface and a part of it refracts.

Light falls obliquely on the surface of a thick glass slab as shown in the figure. Which statement among the following is correct?

When it travels from one medium to another at an angle, the speed of the part of the light which enters the medium changes and the speed of the rest of the wave changes later. 

If the absolute refractive index of glass is $3/2$ and that of water is $5/4$, then find the ratio of speed of light in water and to that in glass.

Light travels from air to glass slab having refractive index of $1.50$. The speed of light in glass will be $\_\_\_\_\_\times {10}^8$ $\mathrm{m}/\mathrm{s}$?

(Speed of light in vacuum is $3\times {10}^8 \mathrm{m}/\mathrm{s}$.)

If a ray of light passes obliquely from one medium to another, it does not suffer any deviation.

The angle of deviation produced by the glass slab is

Which of the following is Snell 's law.

The refractive index of a transparent material is $\raisebox{1ex}{$3$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$. The speed of the light in that medium is _____ $\raisebox{1ex}{$\mathrm{km}$}\!\left/ \!\raisebox{-1ex}{$\mathrm{s}$}\right.$.

Speed of light in vacuum is _____ $\raisebox{1ex}{$\mathrm{km}$}\!\left/ \!\raisebox{-1ex}{$\mathrm{s}$}\right.$.
