Reflection:

• Think of reflection like looking in a mirror. When you stand in front of a mirror, you see your own image because the light from you bounces off the mirror and comes back to your eyes.
• In science, reflection is when light hits a shiny or smooth surface, like a mirror or water, and bounces back in an organized way. It's like light saying, "Hello!" and coming back to you.
• So, when you see your face in the mirror or your reflection in a pond, that's reflection at work.

Refraction:

• Now, let's talk about refraction. Imagine you have a straw in a glass of water. When you look at the straw from the side, it appears bent or broken at the surface of the water.
• Refraction is when light bends or changes direction as it passes from one material (like air) into another material (like water or glass). It's like light taking a little detour because it's moving through something different.
• So, when you see the straw looking weird in the glass of water, that's refraction happening because the light is changing direction when it goes from the water into the air.

Key Points:

• Reflection is like a light bounce-back when it hits a smooth or shiny surface, like a mirror.
• Refraction is like light bending when it goes from one material into another, like from air into water.

These two things help us understand how light behaves when it meets different objects or materials, and they create cool optical effects like reflections in mirrors and the bending of objects in water.
