In this chapter, we will be learning about light and optics. We will start by understanding how images are formed by lenses. We will learn about convex lenses, which concentrate light, and concave lenses, which spread light. We will also learn how to determine the focal length of a convex lens using a remote object.
Next, we will study optical equipment such as telescopes and microscopes. We will learn how final images are formed by these devices. Additionally, we will have the opportunity to design and build a simple telescope. This will give us a hands-on experience and a deeper understanding of how optical equipment works.
