Question

Why thunder of lightning is heard moments after the flash is seen?

Answer 1

When lighting the sound of light is heard late and the flash of light see before because the light speed is greater 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.
