Yes distance traveled by light in one year is called light year.

Light year is a unit of distance 'and one light year is 9.46*10^15m.

Light year is a unit used to measure astronomical distances.

Yes, light year is the unit of distance. It is the distance travelled by light in one year is called light year.

1 light year is equal to 9.64*10^15m.

Light year means distance, it is used to measure the distance between any two eg:distance between the sun and the earth

The distance travelled by the light in one year is called Light year,so Light year is a unit of distance.

The light year means the light travels the distance in 1 year ..in quantum physics light it treated as a photon particle ,the rest mass of the photon is zero.and it's has speed of light,C

since form classical mechanics
S=VT { v be the velocity ,and T be the time and S be the distance )_____________________{1}
for photon V=C and for light year T=365 days =365*24*3600 sec
if s be the distance that light/photon travels in 1 year the
s follows form the equation 1. so if
c in SI units that S has the unit of meter.

It is unit of distance used in Astronomy or distance traveled by ray of light in Vaccum during 1 year.

Light year is The distance traveled by light in space for 1 year with the speed of 3 lack KM per sec.

And it is a measure of distance for spacecrafts.
