Answer:
Lightning is seen earlier and thunder is heard later because the speed of sound is 330 m/s and the speed of light is 300,000,000 m/s. Light travels faster than a sound. Thus, light from the lightning reaches first to you. The sound from the lightning takes longer to reach and hence heard later....
