Question

Flash and thunder are produced at same time. But thunder is heard a few seconds later. Why?

Answer 1

because speed of light is more than the speed of sound

Answer 2

☆$\red {HELLO\:DEAR}$☆

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.
