Sound produced by a thunderstorm is heard $10\ s$ after the lightning is seen. Calculate the approximate distance of the thunder cloud. $(Given\ speed\ of\ sound=340\ ms^{-1})$.
The sound of a thunderstorm is heard after light. It is because the speed of light $(3\times10^8\ ms^{-1})$ is more than the speed of the sound.
Speed of the sound $v=340\ ms^{-1}$
Time taken to reach the sound $t=10\ s$
Therefore, distance between the thunder cloud and observer $s=vt$
$=340\ ms^{-1}\times 10\ s$
$=3400\ m$
$3.4\ km$
