Question

convert 1 light year into meter? by full process​

Answer 1

Explanation:

One light year is defined as the distance travelled by light in one year in vacuum.

Speed of light in vacuum  c=3×10^8 m/s

Time in one year  t=1 year=365×24×60×60=3.1536×10^7 s

Thus distance travelled by light in one year   d=ct

⟹ d=3×10^8×3.1536×10^7= 9.5×10^15

Answer 2

Answer:

1 light year is = 9.46×10¹⁵ m
