Question
A child was observing the thunderstorm from the glass window of his room. What would he feel first?
- He would hear the sound of thunder
- He would see the lightning
- He would experience both 1 and 2 at the same time
- None of the above
Hint:
Speed of light is faster than that of sound.
The correct answer is: He would see the lightning
- Speed of light is much faster than the speed of sound.
- Speed of light= 3×108m/s and speed of sound is around 330m/s.
- Therefore, he would see the lighting first.
- So, the correct option is b.
