A monochromatic ray of light passes from air to glass. The wavelength of light in air is λ, the speed of light in air is
(a) The relation between speed of light in air c and in glass v is given by c/v = =1.5 (b) The wavelength of light in glass (λ1) μ = λ/λ1 = λ/1.5

When a ray of light from air enters a denser medium, it: (a) bends away from the normal
The ray of light bends towards the normal. Reason: As the speed of light decreases in the denser medium, it bends towards the normal.
