Question

Distance of light travel the distance from moon can be found with the help of mirrors left on the moon by astronaut.A pluse of light is sent to the moon and returns to earth in 2.562s

Answer 1

Answer: 384,300,000 m

Step-by-step explanation:

Speed
`S` is mathematically expressed as:

`S=(d)/(t)`

Where:

`S=c=3(10)^(8) m/s` is the speed of light

`d` is the distance traveled

`t=(2.562 s)/(2)=1.281 s` since
`2.562 s` is the time it takes to the pulse to go the moon and return.

Finding
`d`:

`d=c t`

`d=(3(10)^(8) m/s)(1.281 s)`

Finally:

`d=384,300,000 m`
