ABCD represents a glass slab and PQRS indicates the path of a light ray passing through the slab. If the refractive index of the glass is $\sqrt{3}$, find the lateral displacement (x).

Q. Refractive index of a rectangular glass slab is $\mu =\sqrt{3}$. A light ray incident at an angle ${60}^{\circ }$ is displaced laterally through $2.5\text{cm}$. Distance travelled by light in the slab is

Q. A ray of light strikes a glass slab 5 cm thick, making an angle of incidence equal to ${30}^{\circ }$. Construct the ray diagram showing showing the emergent ray and the refracted ray through the glass block. The refractive index of glass is 1.5. Also, measure the lateral displacement of the ray. Take $\sin {19.5}^{\circ }=1/3$.

Q. When the same monochromatic ray of light travels through glass slab and through water, the number of waves in glass slab of thickness $6cm$ is same as in water column of height $7cm$. If refractive index of glass is $1.5$ then refractive index of water is :

Q. A ray of light is incident on one face of a transparent slab of thickness 15 cm. The angle of incidence is 60${}^o$. If the lateral displacement of the ray on emerging from the parallel plane is 5$\sqrt{3}$ cm, the refractive index of the material of the slab is

Q.
