(1) 8 Min 20 Seconds
(2) 2 Min 10 Seconds
(3) 6 Min 44 Seconds
(4) 4 Min 27 Seconds

Correct Answer : (1) Light from the Sun reaches us in nearly 8 Min 20 Seconds.

Explanation:

Light travels at 3 Lakh km a second at the Earth is 152.06 million km to Sun on average. Hence, the light from the sun takes about 8 minutes 20 seconds to reach the Earth after it has been emitted from the sun’s surface.

The time it takes for light from the Sun to reach planets in our Solar System varies from about 3 minutes for Mercury, to about 5.3 hours for Pluto.

On average, it takes energy between 10,000 and 170,000 years to leave the sun’s interior and then be emitted from the surface as light.

On Earth, sunlight is filtered through the Earth’s atmosphere, and is obvious as daylight when the Sun is above the horizon.
