The speed of light is about 183,000 miles per second, or just under 300,000 kilometers per second. Radio transmissions, which travel at the speed of light, can go from the earth to the moon in under two seconds, but it would take them almost nine minutes to reach the sun. As far as distance, no one has ever theorized that light stops traveling, if unimpaired by a solid substance. It's presumed that it can travel to the known edges of the universe, but it can take it billions of years to get there.
What else can I help you with?
Do neutrinos travel at the speed of light, or do they move at a different velocity?
Neutrinos do not travel at the speed of light, but they do move very close to the speed of light.
What speed do electromagnetic waves travel?
the speed of lightspeed of light
How does the speed of radio waves compare with the speed of infrared waves?
Radio waves travel at the speed of light, which is the fastest speed possible in a vacuum. Infrared waves also travel at the speed of light, so both types of waves travel at the same speed.
What is it that all electromagnetic waves do the same?
All electromagnetic waves travel at the speed of light in a vacuum and can be characterized by their wavelength and frequency.
What are the Four other types of transverse wave that travel at 300000000 ms?
Light waves - electromagnetic waves that can travel through a vacuum at the speed of light. Radio waves - electromagnetic waves used for communication that travel at the speed of light in a vacuum. X-rays - a high-energy form of electromagnetic radiation that can travel at the speed of light. Microwaves - electromagnetic waves commonly used in technology and cooking that can travel at the speed of light.
The light year is measured by?
how far u can travel at the speed of light in a year
How far does the speed of light travel after an hour?
Speed doesn't travel. Light travels.Light goes about 300,000 km in a second; in an hour, it goes 3600 times as far, since an hour has 3600 seconds.
Is it possible to breach the speed of light?
As far as is known nothing with mass can travel at the speed of light. There are 'things' that exceed light speed, such as wave guides, but mass or information cannot do so.
Is it possibie to travel at the speed of light?
Nothing with a rest mass can travel at exactly the speed of light, it would take an infinite amount of energy. Light can travel at that speed because it has zero rest mass. Earlier Answer below So far, we don't know if a human can travel at lightspeed. However, it's easier to travel at the speed of light than to travel through time. New Answer: The problem I always had with the term light speed is that speed is relative. We may be traveling close to the speed of light right now in relation to some other object in the universe.
How far in Light years can a Pulsar travel?
As far as light can travel
Can a person travel at a speed of light?
No. Nothing with mass can travel at the speed of light.
If there is a speed of light what is the speed of dark?
Dark does not exist, it is only the absence of light. Darkness is not an entity, so it does not travel and has no speed. In principle, a shadow or nonentity could "travel" faster than the speed of light. For example, if you pivoted a powerful laser a few degrees the point of light would travel across a screen very far away at a "speed" greater than light. Note that this is not at all faster than light motion. You could achieve a similar effect by casting shadows on things very far away. But none of this is actually a "speed."
Does red light travel longer that the gamma ray?
All electromagnetic waves travel at the speed of light. How far they travel depends on when or whether they hit an object that they cannot pass through.
How do you travel in the speed of light?
You don't. The only objects that can travel at the speed of light are those that ONLY travel at that speed, like photons or gravitons.
What will happen if a man passes a electrmagnetic waves in speed of light?
A man can't travel at the speed of light.A man can't travel at the speed of light.A man can't travel at the speed of light.A man can't travel at the speed of light.
What is meant by light year is how far light travel in one?
It is the distance travelled by light in one year at a speed of 186,000 miles per second
How does the speed of visible light compare with the speed of gamma ray?
Both visible light and gamma rays travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second). Thus, there is no difference in the speed at which visible light and gamma rays travel.
