What are 5 compound words made from moon?
moon beam moon light moon struck moon shine moon rocket
How long did it take to travel to the moon?
If you are a beam of light , it would take you 1.4 seconds. The Apollo spacecraft of the 1960s and early 1970s took 3 days (72 hours) each way.
What is the name of the beam of light used to measure the distance from earth to moon?
Laser
Does it take a long time to get to the moon?
Not really. For a beam of light, it takes just over one second; for astronauts, about three days. If it could occur - Driving a car would take 3 years, and walking would take 7 years.
How long would it take to get to the moon if we were traveling the speed of light?
It would take approx 1.28 seconds.
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
What is the definition of ray in physics?
I think it's one of these a straight narrow beam of light from the sun or moon a beam of heat, electricity, or other form of energy
For the moon to travel at the speed of light how long would it take to orbit the earth?
1 second
Can laser light reached at moon and can reflect back?
Yes. The moon's high albedo is used as a mirror to reflect laser light from the Earth. They more accurately track the orbit and distance of the moon than previous methods. However, in order to have a reflected laser beam that the eye could see (like in a movie) the laser would have to be incredibly strong and have a large beam. No laser currently on Earth is capable of this. However, the moon's albedo is high enough that if such a significantly large laser existed it could reach the moon and be reflected back.
How far away would a beam of light have to be to be able to watch it travel?
This would not be possible for a couple of reasons. First let us set up the following scenario. We will shoot a laser from the Earth to the Moon which will take 1.2 seconds to arrive. You will be observing from 240,000 miles away in a spaceship that is at a right angle to the laser beam. This will make the Moon the same apparent size as it is on Earth. In theory, you should see a laser beam begin from Earth and quickly get longer and longer until it reaches the Moon in 1.2 seconds. The problem is that when we see a laser beam, we are not actually seeing the beam itself, only a small part of the beam reflecting off particles in the laser beam's path. Since space is a vacuum, there are no particles for the beam to reflect off, so we see nothing unless the laser beam is pointed directly at us, which in this case is not. The other problem is that when the laser light is reflected toward us from the particles, it is also scattered and would be much too faint to observe from that distance, even with a telescope.
Why do we have a moon?
because if we didn't have a moon there would be no light.
Name the beam of light used to measure the distance from the earth to the moon?
Lunar Laser Ranging experiment. See related link.
