Question

define on light year distance traveled by light on one year
​

Answer 1

Answer:

light-year is the distance a beam of light travels in a single Earth year, or 6 trillion miles (9.7 trillion kilometers).

Answer 2

Light year -

• A light-year is a unit of distance, and one light-year is equal to 9.4 × 10¹² kilometers.
• It is used to measure a distance of a very large quantity.
• It can also be defined as a unit of distance equal to the distance that light travels in one year.

The distance travel by the light on one year -

• The light moves with the velocity of 3×10⁸ m/s, and so in one year it travels 10 trillion kilometers, so it is approximately equal to 1 trillion light-years.

• So, the distance travel by light in one year is 1 light-year.
