Question

if t is the time interval between sending laser pulses from the earth and reflection from the surface for the moon and c the velocity of laser pulses then the distance of earth is.​

Answer 1

Answer:

time = t

velocity = c

distance = 2x

velocity = distance/time

c = 2x/t

2x = ct

x = (c × t)/2

Answer 2

Answer:

Explanation:

distance covered by the laser pulse is 2d ,,,

so 2d=ct

d=ct/2
