Q: What happens to the speed of light as it passes from air into water? (2022)
Solution:
The speed of light decreases when it passes from a less dense medium (air) to a denser medium (water).
Steps: 4
Show Steps
Step 1: Understand that light travels at a certain speed in air, which is faster than in water.
Step 2: Recognize that air is less dense than water.
Step 3: When light moves from air (less dense) into water (denser), it slows down.
Step 4: Conclude that the speed of light decreases when it enters water from air.
