At a time when it is cloudy, there may be frequent thunder and lightning. The sound of thunder takes some time to reach you after you see the lightning.
Can you answer why this happens?
Measure this time interval using a digital wristwatch or a stopwatch.
Calculate the distance of the nearest point of lightning. (Speed of sound in air = \(346\) \(m\ s^{-1}\)
Can you answer why this happens?
Measure this time interval using a digital wristwatch or a stopwatch.
Calculate the distance of the nearest point of lightning. (Speed of sound in air = \(346\) \(m\ s^{-1}\)
The formula to calculate the distance is,
Let us take the time interval between the lightening and thunder is \(6\) \(s\),
Distance of the nearest point of lightning \(=\) \(m\)
