Answer 1

Answer:

Light travels faster than sound. So, sound of thunder take more time to reach us and hence we hear the sound of thunder after we see the lightning.

Suppose, you see a lightning ‘t’ time before you hear the roaring sound of thunder and ‘S’ be the distance between you and the near point of the lightning. Since, velocity of light (299792458 m/s) is very large compared to the speed of sound. We can neglect the time interval between the lightning and the instant we see. So, the distance the sound had to travel with speed 346 m/s in time ‘t’ s to reach you is,

S = 346t m
