Question

When light passes from a denser material to a less dense material
Options
A light slows down and bends toward the normal.
B light slows down and bends away from the normal
C light speeds up and bends toward the normal
D light speeds up and bends away from the normal.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

When light goes from a denser to a rarer medium, it speeds up (since speed is higher in a less dense medium). According to Snell's law, the light will bend away from the normal.

Hint

Remember that speed of light is higher in a less dense medium. Consider how Snell's law (n₁ sin i = n₂ sin r) applies when n₁ > n₂.
