The 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)
3.4 km
Time taken by the sound after lightening = 10 sec
The speed of the sound = 340 m/s.
Distance traveled =s
speed=distancetime
distance = speed x time
distance,s=340 ms−1×10s=3400 m=3.4 km
