Laser Pointer
If I shine a laser pointer at the moon would it dazzle an astronaut on the surface?
A handheld laser pointer. I know they come in a range of colours and powers. What would the astronaut see if they looked at Earth at the time the light reached the moon?
No, it would not be visible on the Moon. There is a science experiment where powerful lasers on Earth are aimed at the retro-reflector mirrors on the Moon, and we get only a few photons back each second.
A 15 watt laser spreads out to about 7 km by the time the beam gets to the moon (your laser pointer spreads out a lot more than that). The power of the beam on the Moon is only 0.15 microWatts!
