Question

A light year is defined as the distance that light can travel in 1 year. What is the value of 1 light year in meter? Show your complete work. [Note: light travels 3 x 10^8 m in 1s.]

Answer 1

d=9.462×10^15 meters

Step-by-step explanation:

Relation between distance, temps and velocity:

d=v*t

t=1year*(365days/1year)*/(24hours/1day)*(3600s/1h)=31536000s

So:

1 light year=d=3*10^8m/s*3.154*10^7s=9.462×10^15 meters
