The expected time period between the observations of lightning and thunder would be 22.5 s.
How to calculate the time of sound waves?
The time taken by sound to reach a certain position can be calculated by the speed formula,
Where,
- speed = 0.343 km/s
- distance = 7.5 km
- time = ?
Put the values in the formula,
Therefore, the expected time period between the observations of lightning and thunder would be 22.5 s.
