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

I'm learning about light in my science class. What is reflection?<|im_end|>
<|im_start|>assistant
Reflection is when light bounces off a surface. For example, when you look in a mirror, the light from your face bounces off the mirror and back to your eyes, so you can see yourself.<|im_end|>

That makes sense. What is refraction?<|im_end|>
<|im_start|>assistant
Refraction is when light passes from one material into another and changes direction. This is why objects appear bent when they're in water – the light is being refracted, or bent, as it passes from the air into the water.<|im_end|>

I see. Can you give me an example of refraction in everyday life?<|im_end|>
<|im_start|>assistant
A common example of refraction is a straw in a glass of water. When you put a straw in a glass, it looks like the straw is bent at the water's surface. This is because the light is being refracted, or bent, as it passes from the air into the water.<|im_end|>
