Question

A beam of light in air is incident on a glass slab at an angle of incidence θ_i < 90°. After entering the glass slab, the beam of light A)does not change its path. B)follows the normal to the glass slab. C)bends away from the normal drawn at the point of contact. D)bends closer to the normal drawn at the point of contact.
