Question

Select the statement that correctly describes how light travels.. -Light cannot travel in a vacuum because it travels slower when the light source is moving. . - Light cannot travel in a vacuum because the light source is stationary. . - The speed of light, traveling in a vacuum, will not change if the light source is moving. . - Light traveling in a vacuum changes speeds when the light source moves. .

Answer 1

"The speed of light, traveling in a vacuum, will not change if the light source is moving" is the statement among the following choices given in the question that correctly describes how light travels. The correct option among all the options that are given in the question is the third option or the penultimate option.

Answer 2

Answer

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

Explanation

Light is in the list of electromagnetic spectrum. Electromagnetic waves do not require a material medium for propagation. This means that they can travel in vacuum and so is light.

The speed of light is always constant and it does not depend on the source. So the correct statement about light is; the speed of light, traveling in a vacuum, will not change if the light source is moving.
