How Does Refraction and Diffraction (The Bending Of Light) Work?

Light bends when it moves from one place to another, this is refraction and diffraction, two kinds of bending.

Imagine you're walking on a sandy beach, and then you step into the water. Your legs feel like they’re moving slower in the water, right? That’s kind of what happens with light. When it goes from air to water or glass, it changes speed, and that makes it bend, just like your legs seem to bend when you walk from sand to water.

Refraction is when light bends as it moves through different materials, like from air into water or a prism. It’s why a straw in a glass of water looks bent, the light changes direction as it goes through the water.

Now imagine you're walking toward a fence with lots of small holes in it. You can see through the holes, and your shadow spreads out on the other side, that's diffraction! Light waves spread out when they go through small openings or around corners, just like how sound waves make music seem to come from everywhere when you're near a big speaker.

So both refraction and diffraction are ways light bends, one is about changing speed in different materials, the other is about spreading out through holes or around edges. Light bends when it moves from one place to another, this is refraction and diffraction, two kinds of bending.
