Identify the statement that correctly represents how light travels.

Light can travel in a vacuum, and the speed at which it travels decreases if the source is moving away.

Light cannot travel through a vacuum because it travels slower when the light source is moving.

Light travels at a constant speed through a vacuum, even if the light source is moving.

Light travels at different speeds when the light source is moving in the same direction and cannot travel in a vacuum.

Tony George · Answer 1

Light travels at constant speed through a vacuum, even if the light source is moving.

Explanation:

Light have both wave and particle nature. Light uses its wave nature to pass through the mediums by vibrating. Light behaves as particle when it passes through the vacuum. So, light can pass through the vacuum because it does not need any medium to travel. The speed of light in vacuum is same for all the observers regardless of their relative motion with respect to source.
