A laser light beamed at the Moon takes 2.56s and to return after reflection at the Moon's surface. What will be the radius of lunar orbit?

Text Solution

Verified by Experts

t = 2.54s
`:.` t = time taken by laser beam to go to the Moon = `t/2`
Distance between Earth and Moon = `d = c xx t/2 = 3 xx 10^(8) xx (2.56)/(2) = 3.84 xx 10^(8)` m
