Why is some thunder a sudden loud bang (with minor echos), while other times it’s a long drawn-out roll that goes on & on? Is it simply how close I am to the lightning, or is there more to it?
In: Physics
Lightning generate sounds along a whole arc it travel almost at the same time. And the length of this path can be pretty long. This means you’re receiving sounds from different point sources. If every point on the arc are mostly has roughly the same distance to you, the sound is sharp; if it’s not, it’s a drawn out rumbling.
