It takes one second for every 299,792 km (186,282 miles) it has to cover.
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.
Gamma Rays will travel as long as they have energy
Sound can travel as long as there is something for it to travel through. This could be a gas (such as air), a liquid (such as water) or a solid (such as a metal). In outer space there is no air for the sound to travel though, so astronauts can not talk with each other unless they use a radio. Radio waves and light waves can travel through space, that is why we are able to receive light from the sun. Source: www.examville.com
The question is irrelevant, since sounds cannot be transmitted through space.
Electromagnetic waves, such as light waves and radio waves, can be transmitted in a vacuum because they do not require a medium to travel through. These waves propagate through the vacuum of space and can travel long distances without the need for a medium.
Because I'm a genius.
With present technology it only takes a few minute to reach 'space'. To travel elsewhere would depend on your destination.
Radio waves are the most commonly used electromagnetic signals for communication through space. These waves have long wavelengths that can travel long distances without getting absorbed by the Earth's atmosphere. Additionally, microwaves and infrared signals are also used for specific space communication purposes.
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.
Waves cannot transport matter over long distances. They can only transmit energy through a medium or vacuum. For example, light waves can travel through space, but they cannot carry physical objects.
8.31 minutes @ the speed of light.
this question makes no sense. Do u mean a 'lighyear'?
