Draw the course of rays for correcting a hypermetropic eye.

Draw the course of a rays for tracing image of an object held between pole and principal focus of a concave mirror. State the position and nature of image formed. or Draw the course of rays for tracing image of an object held between optical centre and principal focus of a convex lens. State the nature of image formed.

Make a diagram to show how hypermetropia is corrected. The near point of a hypermetropic eye is 1 metre . What is the power of the lens required to correct this defect ? Assume that the near point of the normal eye is 25 cm .

A person uses a lens of power +3D to normalise vision. Near point of hypermetropic eye is

(a) Make a diagram to show how hypermetropia is corrected (b) The near point of a hypermetropic eye is 1 m. What is the power of the lens required to correct this defect ? Assume that the near point of the normal eye is 25 cm .
