Draw the ray diagram to show the location of the principal focus of a convex mirror. Identify the pole and centre of curvature.

A ray passing through the principal focus of a concave mirror or a ray which is directed towards the principal focus of a convex mirror, is reflected back along the same path.

Draw the ray diagram to show the location of the principal focus of a Convex mirror, Identify the pole and Centre of Curvature.

Define principal focus of a spherical mirror.

A thin rod of length (f)/(3) is placed along the principal axis of a concave mirror of focal length f such that image which is real and elongated just touches the rod. What is the magnification?

A diminished real image is obtained when the object is placed between centre of curvature and focus of a concave mirror.

Mention two uses of concave mirror.

If an object is placed at the focus of a concave mirror, where is the image formed?

Show with a neat diagram, the direction of the reflected ray in case of a concave mirror if the incident ray is : Parallel to the principal axis,
