Hello! How can I help you today?<|im_end|>

I was wondering about light and how it bends. What is that called?<|im_end|>
<|im_start|>assistant
That's called refraction. Refraction happens when light passes from one material to another and changes direction.<|im_end|>
<|im_start|>user
That makes sense, I think I've seen it happen with a straw in a glass of water. But why does it bend?<|im_end|>
<|im_start|>assistant
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.<|im_end|>

Oh, I get it now. Thanks for explaining that to me.<|im_end|>
<|im_start|>assistant
You're welcome! I'm glad I could help clarify refraction for you.<|im_end|>
