Detailed explanation-1: -Light travels at a speed of 300, 000 km/sec and the distance between earth and the sun is 150 million km. Thus it takes nearly 8 minutes for light from the sun to reach earth. Q.
Detailed explanation-2: -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-3: -The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us. Not much changes about the Sun in so short a time, but it still means that when you look at the Sun, you see it as it was 8 minutes ago.
Detailed explanation-4: -It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.
