How long does it take to go to the moon by the speed of light?

At its average distance from the earth, the moon is 1.28 light seconds away.


How fast does light travel from the sun to the moon?

Light takes about 1.28 seconds to travel from the Sun to the Moon. This speed is approximately 299,792 kilometers per second, which is the speed of light in a vacuum.


For the moon to travel at the speed of light how long would it take to orbit the earth?

It takes about 1.28 seconds for light to travel from the moon to Earth. So if the moon were to travel at the speed of light, it would complete an orbit around the Earth in approximately 1.28 seconds.


When travelling at the speed of light's one can reach the moon in?

1.27 seconds


How far is earth is from the moon in years?

Depends on the speed. At the speed of light, it takes a little over a second.


How long does light take to travel from the Earth to the Moon if the distance between them is 384000 km?

The speed of light is 300,000 km/second. If you divide the distance by this speed of light, you get the time in seconds: 1.28.


How long would it take to get to the moon if you were traveling from the Earth at the speed of light?

About 1.5 seconds


How long would it take electricity to travel from the earth to the moon?

I would imagine the speed of Electricity in a bolt of lightening is very close to that of light ... light travels at 187000 mph...The moon is 238,857 miles from earth. If you divide the speed of light from the distance to the moon, you get about 1.27 hours (1 hour, 16 minutes, and 20 seconds


When did scientists attempt to measure the speed of light?

Are you asking when the speed of light was first estimated, or are you asking when the speed of light was first actually measured?


How many miles per second does light travel from the moon?

The speed of light in a vacuum is the same, whether it goes to the Moon or elsewhere. By some theories, light travels at "c" relative to the local gravitational field. So if somewhere you found a gravitational field moving quickly, the light in that field might travel faster than the light in a different gravitational field. This is not -- not! -- standard physics. (yet).


How long at the speed of light would it take to get to the moon?

Laser light propagates at the same speed as radio waves or any other form of electromagnetic radiation. That is 186,282.4 miles per second. The moon averages about 239 thousand miles. Light, therefore requires roughly 1.3 seconds to cross the gulf dividing the earth and moon.


How long it takes for a particle from the moon to hit earth?

Well, if it is a particle of light (a photon) it takes about a second and a half. If it is any other particle, one that does not move at the speed of light, then you have to define a speed for it.
