Q1 Lightning comes before thunder is heard.​

Answer 1

Answer:

If we are watching the sky, we see the lightning before we hear the thunder. That is because light travels much faster than sound waves. We can estimate the distance of the lightning by counting how many seconds it takes until we hear the thunder. It takes approximately 5 seconds for the sound to travel 1 mile.

Answer 2

Thunder and lightning happen at approximately the same time, but as you have heard, lightning travels faster than thunder (even though it is moving a supersonic speeds) and thus we see the flash before we hear the thunder.
