Chapter Notes
Chapter 9: Light – Reflection and Refraction explores the behavior of light. It begins with the laws of Reflection by spherical mirrors (concave and convex). Students learn to draw ray diagrams to determine the position and nature of images formed by mirrors. The Mirror Formula and magnification are introduced for numerical problem-solving. The second half covers Refraction, explaining the bending of light as it passes between media, the Refractive Index, and refraction through glass slabs and spherical lenses. The Lens Formula and the concept of Power of a Lens are key topics for exams.
