A spherical mirror is that mirror whose reflecting surface is the part of a hollow sphere of glass. Spherical mirrors are of two types: concave mirror and convex mirror. In a concave mirror reflection of light takes place in the bent in surface or concave surface. The inner shiny surface of a spoon is an example of a concave mirror. In a convex mirror the reflection of light takes place at the bulging-out surface or convex surface. The back side of a spoon is an example of convex mirror.

Answer:
Explanation:
Rule 1: When a ray of light which is parallel to the principal axis gets reflected, it passes through its focus.
Rule 2: When a ray of light passes through the centre of curvature, it gets reflected back along the same path.
Rule 3: When a ray of light passes through the focus, it becomes parallel to the principal axis after reflection.
Rule 4: A ray of light which is incident at the pole is reflected back making the same angle with the principal axis.
