True
False
They occur at the same time but we see light first and hear sound later because the speed of light is nearly million times greater than that of sound.
Lightning and thunder occur at the same time and at the same distance from us.Yet, lightning is seen earlier than thunder is heard. Can you explain this? [2 MARKS]
Explain why, the flash of lightning is seen first but the sound of thunder is heard a little later (though lightning and thunder take place in the sky at the same time and same distance from us).
