Things to remember

• A mirror whose polished, reflecting surface is a part of hollow sphere of glass, is called a spherical mirror. One side of it is made opaque and another side acts as a reflecting surface.
• Concave mirror : A mirror which is a part of sphere and is polished from the outer surface such that its reflecting side is inward is called a concave mirror.
• Convex mirror : A mirror which is a part of sphere and is silver polished from the inner surface such that its reflecting side is outward is called a convex mirror.
