Refraction of Light

(i)A ray of light incident on an equilateral glass prism shows the minimum deviation of $30°$. Calculate the speed of light through the glass prism.

(ii) Find the angle of incidence at face AB so that the emergent ray grazes along the face AC.

Write Snell's Law of refraction.

The refractive indices of glycerine and diamond with respect to air are $1.4$ and $2.4$ respectively. Calculate the speed of light in glycerine and diamond. From these results calculate the refractive index of diamond with respect to glycerine. 

The refractive index of glass with respect to air is $\frac{3}{2}$. The refractive index of air with respect to glass will be:

Derive a relation between angle of emergence and angle of incidence on refraction due to a glass slab.

A ray of light in medium of refractive index ${\mu }_1$ is partly reflected and refracted at the boundary of a medium of refractive index ${\mu }_2$ as  shown in the figure. If $\angle BOC=90°$, the value of angle $i$ is given by

How is the Refraction through the glass slab different from the Refraction through prism?

How is the refraction through glass slab is different from the refraction through prism?

Refractive index of glass wrt water is $\frac{5}{4}$ and R.I. of water wrt air is $\frac{4}{3}$ then what is R.I. of glass wrt air?

The refractive index of glass with respect to water is $\frac{5}{4}$ and the refractive index of water with respect to air is $\frac{4}{3}$. What is the refractive index of glass with respect to air?

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

Explain snells law

A glass slab is placed over a piece of paper on which VIBGYOR is printed with each letter in its corresponding colours. The colour that appears to be raised maximum is :

A light ray enters from medium A to medium B as shown in the figure. The refractive index of medium A relative to B will be

A student performs the experiment on tracing the path of ray of light passing through a rectangular glass slab for different angles of incidence. He measures the angle of incidence $\angle i$, angle refraction $\angle r$ and angle of emergence $\angle e$ for all his observations. He would find that in all cases.

Assertion: If the refractive index of the medium is high (denser medium) the velocity of the light in that medium will be small.

Reason: Refractive index of the medium is inversely proportional to the velocity of the light.

When light undergoes refraction through a rectangular slab, show the refracted ray.

Assertion(A): Light does not travel in the same direction in all the media.

Reason (R): The speed of light does not change as it enters from one transparent medium to another.

The ratio between the speed of light in medium to speed in vacuum is the refractive index. When light travels in a medium other than the vacuum, the atoms of that medium continually absorb and re-emit the particles of light, slowing down the speed of light. 

The refractive index of glass is $1.5$. If the light is incident on the glass at $45°$ from the air $\left(n=1\right)$, calculate the angle of emergence.

The velocity of light in a medium is $1.5\times {10}^8 \raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{$\sec $}\right.$ what is the refractive index of the medium with respect to air, if the velocity in air is $3\times {10}^8 \raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{$\sec $}\right.$
