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. A ray of light is incident on a parallel slab of thickness $\left(t\right)$ and refractive index $\left(n\right)$. If the angle of incidence $\left(i\right)$ is small, then the lateral displacement of emergent ray will be

Q. Parallel side glass slab of thickness $8\text{cm}$ is made of a material of refractive index $\sqrt{3}$. When light is incident on one of the parallel faces at an angle of ${60}^{\circ }$ with the normal to the surface and emerges from other parallel face, find the lateral displacement of the emergent ray.
