Question

How far can light travel in 1 year? Remember there are 3.15576 x 10^7 seconds in a single year.

Answer 1

Answer:
`9.465* 10^(15)\ m`

Explanation:

Given

Seconds in a year is
`3.155* 10^7`

We know

`Distance=speed* time`

Speed of light in vacuum is
`3* 10^8\ m/s`

So distance traveled
`=3* 10^8* 3.155* 10^7`

`distance=9.465* 10^(15)\ m`
