Question

A loud crashing sound is heard after lighting .why?

Answer 1

Answer:

It is because light travels faster than sound that we see lightning before we hear thunder.

Answer 2

It’s because the amount of electrical energy that flows from the cloud to the ground is so enormous: it’s like a very big waterfall of electricity.

The louder the sound that you hear, the closer you are to the lightning. Light travels through air much faster than sound. That’s why sometimes you see the lightning flash first and then you hear the thunder a few seconds later. If you see the lightning and hear the thunder immediately, then the lightning is very close to you.
