Cleo stated that light travels through air in straight paths, and when it moves from air to water, light changes direction, speeds up, and bends toward the normal.
Answer
A
Light travels through air and water in angled, scattered paths.
B
Light does not change direction when it moves from air into water.
C
Light slows down when it moves from air into water.
D
Light bends away from the normal when it moves from air into water.
Explanation
Light travels more slowly in water than in air. As it enters water, it bends toward the normal, so Cleo’s claim that it speeds up is incorrect. Choice C correctly states that light slows down when moving from air into water.
