1When light travels from a denser medium to rarer medium, it bends towards the normal.✓
2The incident ray, the refracted ray and the normal to the interface all lie in the same plane.
3The ratio of sine of incidence angle (i) to the sine of refracted angle (r) is a constant for that pair of media.
4When light travels from air (vacuum with velocity c) to a medium with velocity v, then refractive index of the medium can be written as μ = c/v.

Correct answer

When light travels from a denser medium to rarer medium, it bends towards the normal.
