It converges light 2: Convex mirror: ( diverges light) A mirror, its reflecting surface is a part of the outer surface of the sphere. It diverges light rays after reflection. Concepts related to the spherical mirrors: 1. Center of mirror curvature (C): 2. Pole of the mirror (P): 3. Radius of mirror curvature (r): 4. Principle axis of the mirror (CP): 5. Secondary axis of the mirror: 6. Principal focus of the mirror (F): 7. Focal length of the mirror (f):
