Question

What will be refractive index of a medium for which critical angle is 45 degree

Answer 1

Explanation:

Therefore critical angle is 45°. Refractive index is n = c/v where c is velocity of light in vacuum and v in the medium. Since n = √2, v=c/√2.

Answer 2

Explanation:

Refractive index is n = c/v where c is velocity of light in vacuum and v in the medium. Since n = √2, v=c/√2.
