In myopia, light rays from far off objects converge

After reflection, the light rays from a point object at the focus of a concave mirror,

For a myopic (short-sighted) eye, rays from far distant objects are brought to focus at a point

A: Resolution of telescope is high if diameter of objective is large. R: More light rays are converged by objective of large diameter.

As light from a far off star comes down towards the earth :

(i)Draw the type of wave-front that corresponds to a beam of white light coming from a very far off source (ii) What is the relation of a wave-front with a ray of light?

Converging light rays are falling on a convex lens. If the focal length of the lens is 30 cm, then find the position of the image.

Myopia patients cannot see the objects
