Question

Gennerally when rain occurs lighting can be seen first and then sound. But when we turn on television we will hear sound and then light?why?

Answer 1

This is because a television produces the sound earlier than the light.

Answer 2

lighting can be seen first because the light travels 10m/s faster than sound and in t.v we hear first because the people produce the sound first and then the light.
