if the time interval between lightning and thunder is 2 seconds, calculate the distance of the nearest point of lightning. (speed of sound in air is 346 m/s.

Open in App

Solution

Given, speed of sound in air = 346 m/s

Time interval between lightning and thunder = 2 s

Therefore, the distance from the nearest point of lightning = (speed of sound in air) * (time interval between lightning and thunder)
= 346 * 2
= 692 metres (approx.) .
