1. Water: This is a classic example. You can see the bending of light when you put a straw in a glass of water – it appears to be broken at the surface. This is due to the different refractive index of water compared to air.
2. Glass: Glass is used in lenses for cameras, telescopes, and eyeglasses because it effectively bends light. The curvature of a lens allows it to focus light to create images.
3. Ice: Like water, ice also bends light. You can see this effect in the way sunlight refracts through a block of ice, creating rainbows.
