The refractive index of glass for light going from air to glass is 3/2. The refractive index for light going from glass to air will be:(a) 1/3(b) 4/5(c) 4/6(d) 5/2
Glass has refractive index u with respect to air and the critical angle for a ray of light going from glass to air is θ. If a ray of light is incident from air on the glasses with the angle of incidence θ, the corresponding angle of refraction is
