The radio signal sent to the moon was reflected and received on Earth 2.5 s after the transmission. Determine the distance from the Earth to the Moon.
Initial data: t (duration of the radio signal movement to the Moon and back) = 2.5 s.
Reference data: V (speed of propagation of a radio signal in a vacuum) = C (speed of sunlight) = 3 * 10 ^ 8 m / s.
The distance from the Earth to the Moon can be determined by the formula: S = V * 0.5t = C * 0.5t.
Let’s perform the calculation: S = 3 * 10 ^ 8 * 0.5 * 2.5 = 3.75 * 108 m.
Answer: According to the calculation, the distance from the Earth to the Moon is 3.75 * 10 ^ 8 m.
