Name the two types of spherical mirrors. What type of mirror is represented by the:

(a) Back side of a shining steel spoon?

(b) Front side of a shining steel spoon?

Fill in the following blanks with suitable words:

(a) Parallel rays of light are reflected by a ______ to a point called the principal focus.

(b) The focal length of a concave mirror is the distance from the principal focus to the ____.

(c) A______ converges rays of light whereas a ______ diverges rays of light.

(d) For a convex mirror, parallel rays of light appear to ___ from a point called the principal focus

What is a spherical mirror? Distinguish between a concave mirror and a convex mirror.

What is the relation between the focal length and radius of curvature of a spherical mirror (concave mirror or convex mirror)? Calculate the focal length of a spherical mirror whose radius of curvature is 26 cm.

Explain with a suitable diagram, how a concave mirror converges a parallel beam of light rays. Mark clearly the pole, focus and centre of curvature of concave mirror in this diagram.
