Light moves faster than sound Light moves slower than sound Light and sound move at the same speed
I gave my students this multiple choice question: At camp, Raj sees a lightning storm. He sees the lightning before he hears the thunder. What does this show?

Only one answer is correct among these 4 choices:
- Light moves faster than sound
- Light moves slower than sound
- Light and sound move at the same speed

Could you tell me which one is correct?

Light moves faster than sound
