Hey!
user
Hello! How can I help you today?
assistant
I was wondering about light and how it bends. What is that called?
user
That's called refraction. Refraction happens when light passes from one material to another and changes direction.
assistant
That makes sense, I think I've seen it happen with a straw in a glass of water. But why does it bend?
user
It bends because light travels at different speeds in different materials. When light passes from air into water, it slows down and changes direction, causing the straw to appear bent.
assistant
Oh, I get it now. Thanks for explaining that to me.
user
You're welcome! I'm glad I could help clarify refraction for you.
