Therefore, the lightning is approximately one kilometer distant for every three seconds that elapse between the visible flash and the first sound of thunder (or one mile for every five seconds). In the same five seconds, the light could have traveled the Lunar distance four times. (In this calculation, the initial shock wave, which
