A tiny laser beam is directed from the Earth to the Moon. If the beam is to have a diameter of 2.50 m at the Moon, how small must divergence angle be for the beam? The distance of Moon from the Earth is 3.8×10^8m......how to solve this question and is it included in salybus??

Use the formula theta=d/L =2.50/3.8EXP8 =6.58EXP-9 rad. is the answer
