Spherical Mirrors - Class 12 Ray Optics (Set 2)
Module 1: Spherical Mirrors and Terminology Spherical mirrors are a segment of a hollow sphere with reflecting surfaces. They are of two types: (1) Concave Mirror: Reflective surface is curved inward. (2) Convex Mirror: Reflective surface is curved outward. Important terms include: - **Pole (P)**: The center of the mirror's surface. - **Focus (F)**: The point where parallel rays converge (concave) or appear to diverge (convex). - **Center of Curvature (C)**: The center of the sphere from which the mirror is made. - **Focal Length (f)**: Distance between the pole and focus. - **Principal Axis**: A straight line passing through P and C.
