Question:

Light in a vacuum statement.?

02.04]Which statement is correct? Light can travel in a vacuum, and it travels faster if the light source is moving. Light can travel in a vacuum, and its speed is constant if the source is moving or stationary. Light can travel in a vacuum and will travel faster if the light source is moving. Light can travel in a vacuum, and it travels more slowly if the light source is stationary.

Answer:

The speed of light is constant in vacuum and unaffected by the speed of the source emitting the light! Also, light does not need a medium to travel! So the correct statement would be: Light can travel in a vacuum, and its speed is constant if the source is moving or stationary. The correct statement out of the bunch you have added under additional details would be: Light waves can travel in a vacuum and travel at a constant speed even if the light source is moving. I hope this helped! :)
