Question

The sound of the thunder is heard a little later than the flash of light us seen

Answer 1

Sound of thunder is heard a little later than the flash of light because the speed of sound is less than the speed of light.
Speed of sound in air at(20°c)=343m/s
Speed of light=299,792,458 m/s

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.
