velocity of light in air and glass are 3.010^8m^-1 inverse 1.810^8m^-1 respectively one is for air and one is for glass.

find the angle of refraction in glass. if the light travel from air to the glass.?

velocity of light in air and glass are 3.0*10^8m^-1 inverse 1.8*10^8m^-1 respectively one is for air and one is for glass.
