One light year is used for measurement of large distances?

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
One light year is defined as the distance travelled by light in one year in vacuum.
$1 \ light  \ year = 9.5\times 10^{15} \ m$
Since, one light year is very large value. Thus one light year is used for measurement of large distance.
