Full Answer

Light travels at the speed of approximately 186,000 miles per second. The Earth is approximately 93,000,000 miles from the Sun. To calculate how long it takes for light to travel from the Earth to the Sun, divide 93,000,000 by 186,000. The answer is 500 seconds. To convert to minutes, divide 500 seconds by 60 since there are 60 seconds in a minute. This gives the answer of 8.333 light-minutes. To convert 8.333 light-minutes to light-years, divide 8.333 by 525,600 (which is 60 minutes x 24 hours x 365 days). This gives an answer of 0.00001585 light-years.

    Why do humans need light?

    A:

    Light is necessary for the survival of life on Earth, as almost all energy used by life is derived from the sun. Plants and algae use light energy in photosynthesis, which provides usable chemical energy for heterotrophic organisms. In addition, without light, the Earth would be completely cold and dark, as even the moon gets its glow from reflecting the sun.
