Question

A glass slab has refractive index ' μ ' with respect to air and the critical angle for a ray of light in going from glass to air is ' θ ' If a ray of light is incident from air on the glass with angle of incidence ' θ ', then the corresponding angle of refraction is

TestHub · Accepted Answer

In the first case θ is the critical angel Hence, sin θ = μ 1 ​ In the second case, s i n r s i n θ ​ = μ ​ ∴ sin r = μ sin θ ​ ∴ sin r = μ 2 1 ​ ∴ sin r = ( μ 2 1 ​ ) ​
