Answer:
accuracy in measured value of distance, d' = 0.015 m
Given:
measured time, t = 0.100 ns = [tex]0.1\times 10^{-9} s[/tex]
Solution:
To calculate the accurate distance to the moon with the reflected lased beam, the distance can be calculated by utilizing the time taken for one round trip;
t = [tex]\frac{2d'}{c}[/tex] (1)
where,
d' = distance
From eqn (1):
[tex]0.1\times 10^{-9} s\ times 3\times 10^{8} = 2d'[/tex]
d' = 0.015 m
