The correct answer is:
B. Refraction
Explanation:
1. Refraction is the wave characteristic that allows us to see objects.
2. Refraction is the bending of a wave as it passes from one medium to another, such as light passing from air into water or glass.
3. When light waves pass through different mediums, like air and glass, they bend or change direction due to the change in speed caused by the change in medium.
4. This bending of light waves is what allows our eyes to see objects that would otherwise be invisible if light traveled in a straight path without bending.
5. So, refraction is essential for our ability to see objects clearly.
