## Introduction to Lenses. Equation of Lenses. Image Formation of Lenses

Why do people use optical glasses? What is the shape of these glasses?

Why normal glasses such as window glasses cannot be used to see better?

What happens when you direct a magnifying glass towards sunlight?

What happens to sunlight when it passes through a magnifying glass?

This tutorial is entirely focuses on lenses as the most important tools in optical systems. Since their mathematical apparatus is not very different from curved mirrors, we will deal more with some technical details that were not discussed in the previous tutorial Mirrors, Equation of Curved Mirrors and Image Formation in Plane and Curved Mirrors. Therefore, the tutorial we will explain now is an extension of the previous tutorial mentioned above.
