Detailed explanation-1: -Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.
Detailed explanation-2: -Light travels at a speed of 300, 000 kms−1 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.
Detailed explanation-3: -It takes time 8 min for light to reach from sun to the earth surface. If speed of light is taken to be 3×108 m s−1, find the order of magnitude of distance from the sun to the earth in km. Q. The average distance between Earth and the Sun is 1.496×108 km and the speed of light coming from the Sun is 3×108 m/s.
Detailed explanation-4: -Using Light Years to Measure Distances in Space If you could travel at the speed of light, it would take you about eight minutes to travel to the sun. If you were to travel at the speed of light to the next closest star, Proxima Centauri, it would take you 4.2 years!
Detailed explanation-5: -If the whole atmosphere is filled with water, the light will take the time (aw=34)
