Question

A light ray travelling in air is incident on the surface of an extradense flint glass block. if the angle of incidence is 60°and the angle of refraction is 30°, then find the refractive index of extradense flint glass.​

Answer 1

Answer:

the refractive index is SINI/SINR = SIN 60°/SIN 30° = √3/2 / 1/2

that equals to √3 OR I.73 (approximate.)
