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

Describe with a suitable diagram, how a convex mirror diverges a parallel beam of light rays. Mark clealy the polw, focus and cente of curvature of convex mirror in this diagram.

Ray diagram for Concave Mirror

Draw ray diagrams to show focus for a concave mirror

The angle of incidence for a ray of light passing throught the centre of curvature of a concave mirror is :

Make lablled ray diagrams to ollustrate the formation of : (a) a real image by a converging mirror. (b) a virtual image by a converging mirror. Mark clearly the pole, focus, centre of curvature and object in each case.

With the help of a ray diagram, show the formation of an image of an object placed between principal focus and centre of curvature of a concave mirror.

a) With the help of a labelled diagram, explain how a concave lens diverges a beam of parallel light rays. Mark the princple axis, optical center, principle focus and focal length of the convex lens on the diagram. b) State whether concave lens and convex lens mirror have in common.

Draw ray diagrams for the cases of images obtained in concave mirrors: A ray diagram for object beyond centre of curvature for a concave mirror.

Explain the ray diagram for image obtained for concave mirror by considering three rays.
