a laser beam is directed at the moon 380,000km from earth. the beam diverges at an angle of 1.4 x 10^-5 rad.?

What diameter spot will make on the moon

Answer 1

Let’s identify what we know:

r = distance = 380,000km

A = angle = 1.4 x 10^-5

The diameter (d) of the spot is given by:

d = r * A

= 380,000km * 1.4 x 10^-5 rad

= 5.32 km

So the spot will have a diameter of 5.32 km.

That’s your answer!
