Question

why do we see lighting before we can hear thunder
​

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

Answer:

Because Light Travels faster Than sound it's approximate speed in air is 3x10^8 m/s whereas speed of sound is exponentially slow than light

i.e. 343m/s
