Question

which of the following best describes light refraction? when a light wave is completely absorbed by a material, when light travels in a straight line and is blocked. when light enters a different medium, slows down, and appears distorted,

Explanation:

Refraction is the bending of light when it enters a different medium. This bending occurs because the speed of light changes in the new medium. When light enters a medium where it slows down (such as from air to water), it bends towards the normal (an imaginary line perpendicular to the surface of the medium). This change in direction can make objects appear distorted.

• The first option describes absorption, not refraction.
• The second option describes the property of light traveling in a straight line and being blocked (like in the case of a shadow), which is not refraction.

Answer:

When light enters a different medium, slows down, and appears distorted.
