how to calculate distance of a light year
Calculations involving light years and distance – Higher
A light year is a distance.
It is the distance light travels in one year.
As light travels at constant speed, the distance light travels in a year can be calculated using the equation:
Distance = speed x time.
time = 1 year = 365 x 24 x 60 x 60 = 31,536,000 s.
