Question

Flash and thunder are produced simultaneously. But thunder is heard a few seconds after the flash is seen, why?

Answer 1

it's just because the speed of light is much greater than speed of sound ie. 300000000 m/s and 340.29 m/s
so the light reached us faster while sound takes some time to travel .

I hope u r satisfied with my answer ..if yes then pls follow me.

Answer 2

• The speed of sound (344 m/s) is less than the speed of light (3 x 10^8 m/s).

• Sound of thunder takes more time to reach the Earth as compared to light.

• Hence, a flash is seen before we hear a thunder.
