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?

Answers (1)

Speed of light is 3 x108 m / s.
Speed of sound is 340 m /s.
Since speed of light is greater than speed of sound, lightning travels faster than thunder. Due to this, light reaches to us faster than sound. Hence, during lightning we see the streak of light earlier than hearing the sound of thunder.
