First let’s talk about what is lightning how does it occur? As we all are familiar to lightning, we know it is a flash of light accompanied by a loud sound. It can also cause death of the people or other living organisms.
Lightning occurs due to the phenomenon of rubbing. It happens when two oppositely charged ions rub against each other to produce electric currents. When a storm occurs the air air present in the surrounding starts moving upwards and they have a collision with the water droplets present in the environment. This droplets become the careers of the electric charge. The rubbing together of these water droplets cause the charge to glow and produce electric currents. Lightning occurs between two oppositely charged clouds or between a cloud and the ground.
It is always notice that the lightning occurs first and then you sound come a few second afterwards. This phenomenon is due to a simple fact that light travels faster than sound in air. The speed of light is the fastest in the air and cannot be matched. It is 3×10( to the power of 8) and therefore we can hear the sound after the lightening.
