Question

Select the statement that correctly represents how light travels.

A. Light cannot travel in a vacuum when the light source is moving.
B. Light cannot travel in a vacuum if the light source is stationary.
C. Light, traveling in a vacuum, changes speeds when the light source moves.
D. The speed of light, traveling in a vacuum, will not change if the light source is moving.

Answer 1

D. The speed of light, traveling in a vacuum, will not change if the light source is moving.

The speed of light in a vacuum is always constant regardless of the speed the source or you are travelling at.

Answer 2

D. The speed of light, traveling in a vacuum, will not change if the light source is moving.

Step-by-step explanation:

A consequence that is obtained from the laws of electromagnetism, that is, Maxwell's equations is that the speed of the electromagnetic radiation does not depend on the speed of the object emitting such radiation. Since light is a form of electromagnetic radiation, if it is emitted by a source that moves very quickly, it would travel as quickly as light from a stationary source.
