Question

3 Moonlight reaches earth in 1.25 seconds only whereas sunlight reaches in 8 min 19 seconds. What is the reason behind this?
​

Answer 1

Answer:

Moonlight, like all light, travels at 300000 km/s in a vacuum. The Moon is (on average) 384000 ...

Answer 2

Explanation:

• The speed of light in vacuum is 299,792,458 m/s. Thus when the distance varies, the time taken by light to cover those distances will also vary.

• The distance of the Moon from the Earth is 384,400 km and thus time taken is 1.25 seconds.

• The distance of the Sun from the Earth is 147.15 million km and thus time taken is 8 min 19 seconds.

Conclusion:

The main reason behind this variation is the distance between the two objects, namely Sun, Earth and Moon, Earth.
