How It Works

Light travels at ~299,792 km/s — essentially instant at any terrestrial distance.

Sound travels at ~343 m/s at 20°C, increasing ~0.6 m/s per °C.

Count the seconds between flash and thunder, multiply by 343 to get distance in meters.

Real lightning has 3-5 return strokes flickering down the same channel ~60ms apart.
