Establish the relation between object distance, image distance and radius of curvature for a concave mirror.

By stating the sign conventions and assumptions used, derive the relation between distance of object, distance of image and radius of curvature of convex spherical surfaces, when refraction takes from optically rarer to optically denser medium.

What is the relation between focal length and radius of curvature of a concave mirror? What is focal length of a plane mirror?

The relation between the radius of curvature (R) and focal length (f) of a concave mirror is……

By giving sign-conventions, derive the lens formula relating object distance, image distance and focal length for a thin convex lens. Draw a ray diagram to show the formation of image of an object placed between optical centre and focus of a convex lens.

Where will the real and inverted image of an object placed at the centre of curvature of a concave mirror will be formed?

When an object is placed beyond centre of curvature of a concave mirror, the image is formed:

Describe with the help of diagram the natrue, size and position of the image formed when and object placed at centre of curvature of a concave mirror.
