About this unit

What's inside our eyes? How do they work? Why do some people wear spectacles? Why do the stars twinkle? In this chapter, we will use the rules of refraction to explore the working of our eyes and their defects. We will learn how dispersion creates rainbows and how scattering creates the blue sky.
