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.

Respuesta :

Answer:

d = 0.479 m

Explanation:

Given that,

The distance light travels in  = 1.6 ns

The speed of light is [tex]2.998\times 10^8\ m/s[/tex]

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

[tex]c=\dfrac{d}{t}\\\\d=ct\\\\d=2.998\times 10^8\times 1.6\times 10^{-9}\\\\=0.479\ m[/tex]

Hence, the required distance is 0.479 m.
