Reflection of Light by Spherical Mirrors

गोलीय दर्पणों द्वारा प्रकाश का परावर्तन

In Class 12 Physics, this topic from Chapter 9, Ray Optics and Optical Instruments, explains how light behaves when it reflects from concave and convex spherical mirrors. Students learn the laws of reflection, pole, centre of curvature, radius of curvature, principal focus and focal length, along with standard ray diagrams. They apply the mirror formula and magnification relation using the Cartesian sign convention to determine image position, size, orientation and nature, and connect these ideas with practical uses of spherical mirrors.
