A ray of light enters a glass block from air at an angle to the normal.
Which statement describes the refracted ray?
It bends towards the normal, so the angle of refraction is smaller than the angle of incidence
It bends away from the normal, so the angle of refraction is larger than the angle of incidence
It does not bend, so the angle of refraction is the same as the angle of incidence
It bends towards the normal, so the angle of refraction is larger than the angle of incidence
