A ray of light travelling in air strikes the glass surface at an angle of incidence 60∘. Find the angle of refraction in glass if refractive index of glass is 32? (given sin60∘=√32 and sin35∘=1√3)
aμg=32=sin isin r Or sinr=sin60∘32 sin r=1√3 r=1√3
Refractive index of glass is 32. A ray of light travelling in glass is incident on glass-water surface at an angle 30° with normal. Will it be able to come out into the water. Refractive index of water = 43.
