Question

Choose the wrong statement.

• A. A ray entering a material of larger index of refraction bends towards the normal.
• B. A ray entering a material of smaller index of refraction bends away from the normal.
• C. A ray oriented along the normal does not bend, regardless of the materials.
• D. Light rays from any submerged object bend away from the normal when they emerge into the air.
• E. When a wave passes from one material into a second material with larger index of refraction, the wave speed increases.

Hint:

Higher refractive index means lower speed of light in that medium.
