Answer:

*If we are watching the sky, we see the lightning before we hear the thunder. That is because light travels much faster than sound waves. ... It takes approximately 5 seconds for the sound to travel 1 mile. If the thunder follows the lightning almost instantly, you know the lightning is too close for comfort!

*Here are some differences: Sound can only travel through a medium (substance) while light can travel through empty space. Sound is a form of mechanical energy caused by vibrations of matter. Light is electromagnetic energy caused by interacting electric and magnetic fields.
