You can estimate the distance of lightning by counting the seconds between the flash and the thunder.
Here's a detailed explanation:
Understanding the Method
The method relies on the fact that light travels much faster than sound. You see the lightning flash almost instantaneously, but the sound of thunder takes time to reach you. By measuring this delay, you can calculate the approximate distance.
The Calculation
-
Count the seconds: Start counting the seconds immediately when you see the flash of lightning. Stop counting when you hear the thunder.
-
Divide by five: Divide the number of seconds you counted by five. This result will give you the approximate distance to the lightning in miles.
Practical Examples
| Seconds Counted | Approximate Distance (miles) |
|---|---|
| 5 | 1 |
| 10 | 2 |
| 15 | 3 |
| 20 | 4 |
| 25 | 5 |
| 0 | Very close |
Important Safety Considerations
- Seek shelter: This calculation is only an estimate. Always prioritize your safety. If the time between the lightning and thunder is short, you are close to the storm and should seek shelter immediately.
- Be aware of the storm's direction: This method only tells you the distance of the lightning. The storm could be moving towards you or away from you.
- Count from a safe location: Make sure you are indoors or in a safe place while you are counting and estimating the distance.
Summary
- Count the seconds between the lightning flash and the thunder.
- Divide the number of seconds by five to find the distance in miles.
By using this simple method, you can estimate the distance to lightning strikes and stay safe during thunderstorms.
