What is lenses Explain in brief
Hello,
Lens - It can be made up of plastic or a glass (or formed from a combination of these two), such that when light passes through it the light rays get refracted.
Light rays from an object present on one side of a lens, when refracted can form an image on the other side of the lens.
Different types of lens;
- A convex/converging lens
- A concave/diverging lens
All the best.
