The Moon is about 1.4 light-seconds away.

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.
My almanac lists the average distance from earth to moon as 384,401 km. Round trip = 768,802 km. Time = (distance) divided by (speed) = (768,802,000) / (3.8 x 108) = (7.68802 x 108) / (3.8 x 108) = 2.563 seconds (rounded)
Yes, a flashlight would work on the moon since it emits light independently and does not rely on any external factors to illuminate. However, the lack of atmosphere on the moon means there would be no air particles to scatter the light, so the beam might appear more focused and clearer compared to Earth.
It would take approx 1.28 seconds.
About 1.5 seconds
A ray of light from the moon is a narrow, beam-like pathway of light that appears to radiate outward from the moon's surface. These rays are created when sunlight reflects off the moon's surface, creating bright streaks that can be observed on 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.
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.
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.
"Shashi" means moon and "Prabha" means light or radiance. Together, "Shashi Prabha" can be interpreted as the radiance or brightness of the moon in Hindi.
