Question -

Lightning and thunder take place in the sky at the same time and at the same distance from us. Lightning is seen earlier and thunder is heard later. Can you explain why?



Answer -

Light travels at the speed of 3 x 108 m/s while sound travels at a speed of 332 m/s i.e., light travels much faster than sound. That is why, lightning is seen earlier and thunder is heard later.
