A laser beam is directed at the Moon, 380,000 km from Earth. The beam diverges at an angle of 4.6×10−5 rad.

1. What diameter spot will it make on the Moon?

  • Physics -

    spot diameter =
    distance * (divergence angle in radians)

    The diameter will be in km if you use the distance in km.
