1. Lenses: The most common example! Glasses, magnifying glasses, telescopes, microscopes, and cameras all use lenses to bend light and focus it, allowing us to see clearly, magnify objects, and capture images.

2. Rainbows: When sunlight passes through raindrops, the light is refracted (bent) and reflected, separating the colors into the beautiful spectrum of a rainbow.

3. Fiber optic cables: These cables transmit data using pulses of light. The light is guided through the cable by refraction, bouncing off the inner walls at a specific angle.

4. Prisms: Prisms are triangular pieces of glass that bend light to separate it into its constituent colors. This is how rainbows are made in a lab!

5. Mirages: Mirages are optical illusions caused by refraction. Hot air near the ground is less dense than cooler air above, and the light rays bend as they pass through these different densities, creating the illusion of water on the ground.
