Can light travel through space?
Yes, light can travel through space because it does not need a medium to propagate.
Why do radio waves change to another wave to reach a satellite in space?
Radiation can move through space because it is made up of light. Unlike sound, it doesn't need a medium (something it can go through) and it can travel through the vacuum. Only light can do this, and radiation can also move through air, obviously.
What form of energy can travel through space at the speed of light?
(a) Electromagnetic waves; that includes light. (b) Gravity waves.
What are waves that travel through space at the speed of light called?
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.
Who proposed the light consisted of particles that travel in straight lines through space?
Isaac Newton proposed that light consisted of particles that travel in straight lines through space.
Who travel faster a radio signal or light in space?
They are the same physical phenomenon, with the same identical speed.
What is the speed of a satellite signal?
The speed of a satellite signal is approximately the speed of light, which is about 299,792 kilometers per second. This means that signals transmitted from a satellite to Earth or vice versa travel at this high speed.
What is the time it takes for a signal to travel?
Communication with spacecraft is by means of radio. Signals travel at the speed of light. At that speed, signal travel one-way to or from the moon takes about 1 and 1/4 seconds. For Mars, depending on where the earth and Mars are in their orbits, radio communication one-way can take up to 22 minutes.
Can light travel through space?
Yes, light can travel through space because it does not need a medium to propagate.
What speed does red light travel in space?
In vacuum, such as in space, red light travels at the same speed as a Channel 47 digital color HDTV signal. That speed is 299,792,458 meters per second, or 186,282 miles per second.
Can light travel through space?
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.
What parts of space can light waves travel through?
Light can travel through any parts of space, there is no part that it is excluded from.
What type of material can travel through space?
Sound and Light can travel through space.
What do light rays need to travel through space?
If light rays did not travel through space there would be no way for them to reach Earth.
How long would it take a radio signal to reach a star that is eleven light years away?
A radio signal would take eleven years to reach a star that is eleven light years away. This is because the speed of light is the fastest speed at which any form of information can travel through space.
What can infrared light travel across?
It can travel across the vacuum of space.
What can light travel thruogh fastest?
"Free Space", the vacuum of space..
