Convex mirrors are made by silvering the inner surface of a part of the hollow glass sphere. Convex mirrors are diverging in nature.
Concave and convex mirror properties
The mirror equation is - \\(1\\over u \\) + \\(1\\over v \\) = \\(1\\over f \\)
Spherical mirrors are used in many daily products.
