Question

वायु में प्रकाश एक सेकण्ड में लगभग कितनी दूरी तय करता है?

Answer 1

Answer:

3 lakh kilometres per second

Answer 2

The distance covered by light wave in air is $d=3\times 10^8\ m$.

Explanation:

In this case we need to find the distance covered by light wave in air. We know that the speed of light in air is $3\times 10^8\ m/s$. Speed is given by :

$v=\dfrac{d}{t}$

$d=v\times t$

$d=3\times 10^8\ m/s\times 1\ s$

$d=3\times 10^8\ m$

So, the distance covered by light wave in air is $d=3\times 10^8\ m$. Hence, this is the required solution.
