# Lightning Formula

## To Find The Distance Of Lightning

d = s * t

Where,

d = distance to lightning

s = speed of sound in air

t = elapsed time between flash and thunder

Note : speed of sound ranges between 1100 to 1200 feet per second.

### To Find The Speed Of Sound

$s = \frac{d}{t}$

### Finding The Time Interval Between Flash And Thunder

$t = \frac{d}{s}$
