C)between media of different optical densities at a right angle.
D)between media of different optical densities at an oblique angle.

Quizplus · Accepted Answer

Refraction occurs when light passes through media of different optical densities at an oblique angle. This is because the speed of light changes as it moves from one medium to another, causing it to bend. When light passes through media of the same optical density, it does not bend, and when it enters a medium at a right angle, it undergoes no refraction (although it may still reflect).
