Light Energy

What is the difference between refraction and reflection?

• Light bends when it is reflected and bounces off when it is refracted.

• Light bounces off when it is reflected and bends when it is refracted.

• Light travels in curved lines when it is reflected and in straight lines when it is refracted.

• When light is refracted, it no longer travels.
