Question

Convert metre into light year.​

Answer 1

Answer:

Light travels at the speed of 3 x 10^8 metres per second. So the distance travelled by light in 1- year is called as 1- light year. It is a unit distance in Astronomy.

So 1- light year= 3 x 10^8 x 86400x365= 9.4608 x 10^15 -metres.

So 1- metre= 1.057 x 10^-16 Light years.
