Question

draw the diagrams of each case to show the position and nature of the image formed when the object is placed. i) at the centre of curvature of a concave mirror ii) at 2F of a convex lens​

Answer 1

Explanation:

The Ray diagram of case the object is at the centre of curvature of concave mirror is in the fig 1.

And the nature of the image is-

same size, inverted and real.

The Ray diagram of case the object is between pole and focus of concave mirror is in fig 2

And the nature of the image is

large,virtual, erect and behind the mirror

The Ray diagram of case the object is infront of convex mirror is in fig 3.

And the nature of the image is

small in size,virtual,erect

The Ray diagram of case the object is at 2f of convex lens is in fig 4.

And the nature of the image is

inverted, same size and real

The Ray diagram of case the object is in front of concave lens is in fig 5.

And the nature of the image is
