The time interval between a lightning flash and the first sound of thunder was found to be 5 s. If the speed of sound in air is 330 m `s^(-1)`, find the distance of flash from the observe.

Text Solution

Verified by Experts

Speed of sound in air = v = `330 ms^(-1)`
Time in which thunder is heard after lighting is seen = t=5s
So, distance between flash and observer
=v x t =(330 x 5) = 1650 m
