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.

Which statement best describes Cleo’s mistake?

Light travels through air and water in angled, scattered paths.
Light does not change direction when it moves from air into water.
Light slows down when it moves from air into water.
Light bends away from the normal when it moves from air into water.

Light slows down when it moves from air into water.

Explanation: water has a higher refractive index than air, so light travels more slowly in water and thus bends toward the normal (not speeds up).
