Who is Refraction Again?

Refraction is when light bends as it moves from one material to another, like when you put a pencil in water and it looks twisted.

Imagine you're running on the playground, and suddenly you have to run through a puddle. You slow down because the puddle feels squishy under your feet. Light does something similar when it goes from air into water or glass, it changes speed, and that makes it bend.

Think of light as a group of kids walking in a straight line. If they suddenly have to walk through a thick carpet (like going from air into glass), they slow down. The kid at the front slows first, so the whole line starts to turn, just like how light bends.

When you look at a straw in a glass of water, it seems to break at the surface, that’s refraction! Your eye sees the light bending as it moves from water into air, making the straw look bent or twisted even though it's not.

It’s like when you're walking on the playground and suddenly you slip on a banana peel, everything changes direction for a moment! Refraction is when light bends as it moves from one material to another, like when you put a pencil in water and it looks twisted.
