Exactly 299,792,458 meters per second. Or about 9.461 times 10 to the power 15 meters in a year.
Yes, light can travel through space because it does not need a medium to propagate.
Light can travel through any parts of space, there is no part that it is excluded from.
Light can travel through space. All the light that we get on the earth's surface; usually travels from the sun through space before it can reach here.
Sound and Light can travel through space.
If light rays did not travel through space there would be no way for them to reach Earth.
It can travel across the vacuum of space.
"Free Space", the vacuum of space..
Yes, light can travel through outer space because it does not require a medium to propagate. In the vacuum of space, light can travel almost undisturbed for long distances until it interacts with matter.
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
Light can travel through outer space because it propagates as electromagnetic waves, which do not require a medium to travel through. This means that light can move through the vacuum of space without any obstacles. This property of light allows it to travel vast distances from its source, such as from stars to telescopes on Earth.
(a) Electromagnetic waves; that includes light. (b) Gravity waves.
