Question

About how far apart must you hold your hands for them to be separated by 1.6 nano-light-second (the distance light travels in 1.6 ns)? Assume that the speed of light is 2.998*108 m/s.

Answer 1

d = 0.479 m

Step-by-step explanation:

Given that,

The distance light travels in = 1.6 ns

The speed of light is
`2.998* 10^8\ m/s`

The speed of an object is given by distance traveled divided by time.

`c=(d)/(t)\\\\d=ct\\\\d=2.998* 10^8* 1.6* 10^(-9)\\\\=0.479\ m`

Hence, the required distance is 0.479 m.
