Here's why:
* Refraction: This is the bending of light as it passes from one medium to another (like from air to glass).
* Lens: A lens is a piece of transparent material (usually glass or plastic) that has at least one curved surface. This curvature causes light to refract, converging or diverging the light rays.
Types of lenses:
* Converging lens (convex lens): It causes parallel light rays to converge at a point called the focal point. This type of lens is used in magnifying glasses, cameras, and telescopes.
* Diverging lens (concave lens): It causes parallel light rays to diverge, making objects appear smaller and further away. This type of lens is used in eyeglasses for nearsightedness and in some telescopes.
Let me know if you'd like more details about how lenses work or specific examples of devices that use them!
