Question

The speed of light is 3.0 x 10^8 m.s^-1. what is the speed in nm.ms^-1 ?

Answer 1

Answer:

$c=3\times 10^{17}\ nm/s$

Explanation:

The speed of light is $3\times 10^8\ m/s$. It is required to convert it into nm/s.

The relation between nm and m is as follows :

$1\ nm=10^{-9}\ m\\\\1\ m=10^9\ nm$

So,

$c=3\times 10^8\ m/s \\\\c=3\times 10^8\times 10^9\ nm/s\\\\c=3\times 10^{17}\ nm/s$

So, the speed of light is $3\times 10^{17}\ nm/s$.
