Detailed explanation-1: -Light travels at a speed of around 3, 00, 000 km s−1 in space. The Earth is 1.5 million km away from the Sun. So, it takes about 8 minutes and 20 seconds for the sunlight to reach Earth.
Detailed explanation-2: -On average, the Earth and Moon are about 150 million kilometres (or 93 million miles) from the Sun! That distance is so large that it takes light eight minutes to reach us (remember that light travels at 300, 000 kilometres per second).
Detailed explanation-3: -At this distance, it takes about 8 minutes for sunlight to reach us – even when it is travelling at about 300 000 km/s. This means that we see the Sun set eight minutes after the event has actually taken place!
Detailed explanation-4: -Q. The Earth is 8.3 light minutes from the Sun. What does this statement mean? (a) 4.3 million kilometres.
Detailed explanation-5: -The correct option is A True The velocity of light is 3×108ms−1. Q. Light travels at a speed of m/s and it takes minutes and 20 seconds for sunlight to reach Earth.
