# Lightning Formula

## Lightning Formula

Physics is a natural science that studies matter and energy, as well as how matter interacts with one another. It also addresses all physical processes and phenomena of a certain system. Physics is the study of nature. If one wishes to comprehend the matter at various levels, say macroscopic and microscopic, fundamental Physics comes out to be a rich mine for studying their nature of motion, behaviour at low and high temperatures, the kinetic energy of molecules, and much more.

Lightning is a natural occurrence that occurs during a thunderstorm when air currents surge and water droplets fall. As a result of this process, positive charges collect towards the top edge of the cloud, whereas negative charges accumulate near the lower edge of the cloud and also near the ground. Lightning is caused by the separation of positive and negative charges. The Lightning Formula is used to calculate the distance at which lightning strikes. The Lightning Formula is determined by the speed of sound in the air and the time difference between thunder and flash.

Air is the ideal medium for sound to travel, and the speed of the sound is affected by elements such as temperature and humidity. The Lightning Formula is influenced by the distance at which lightning strikes, the speed of sound in the air, and the time gap between flash and thunder.

### To Find The Distance Of Lightning

The Lightning Formula is calculated by multiplying the speed of sound in air by the time elapsed between the lightning strike and the thunder. It is represented by the symbol d. Its conventional unit of measurement is metres, which is the same as distance. [M0L1T0] is the dimensional formula for it. It is often referred to as the storm distance formula.

To Find The Distance Of Lightning, d = s * t

Where,

d is the distance to the lightning

s is the speed of sound in air

t is the elapsed time between the lightning flash and thunder

### To Find The Speed Of Sound

The speed of sound is defined as the distance travelled per unit of time by the point of a sound wave, such as compression or rarefaction. Under the same physical conditions, the speed of sound remains constant for all frequencies in a particular medium.

To Find The Speed Of Sound, s=d/t

### Finding The Time Interval Between Flash And Thunder

Because light travels at a far quicker rate than sound, the time it takes for light to reach the earth’s surface is insignificant.

Sound speed in air (V) = 330 m/s

The time it takes for thunder to be heard after lightning is seen (t)
