Question

(a) The distance from Earth to the moon is 3,84,000 Km.
Calculate the time it takes for light to travel that distance.​

Answer 1

Answer:

t takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen.

Answer 2

Answer:

Given Distance between Earth and Moon let D = 384000 km = 384000000 m = 3.84 × 10 ™8

Spread of light Let S = 3 × 10™8 m/s

Speed = Distance/Time

Or time = Distance/speed

Therefore time= ( 3.84 × 10 ™8 m/s)

Or Time = ( 3. 84 / 3 ) s = 1.28 s

Answer) the times it takes for light to travel is 1.28 Seconds.
