A ray of light is incident on one face of a transparent slab of thickn – InterviewSolution

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