Question

Calculate the number of light year in one metre

Answer 1

Answer:

1.057 X 10^(-6)

Explanation:

1 light year is the distance travelled by light in one year

So in a year there are 365.25x86400 sec

= 31557600 sec

Dist = speed of light X time

= 299752458 X 31557600

= 9.641 X 10^15

1 light year = 9.641 X 10^ 15 metres

This means 1 m = (1/9.641)x10^(-15) light year

1 m =1.057 X 10-16 light years
