Image distance from O ?

The graph between object distance u and image distance v from a convex lens is given .The correct option option , from the following ,is

Assertion: In the figure shown |R_1|gt|R_2| .Two point objects O_(1) and O_2 are kept at same distance from the lens. Image distance of O_1 from the lens will be more compared to the image distance of O_(2) . Reason: If medium on two sides of the lens is different, we cannot apply lens formulae directly.

Where is the image formed when an object is at large distance from a concave mirror?

In Fig,, if the image of object O has to coincide with itself, then where must the object be placed at a distance from the lens?

O is a small object placed at a distance D from the eye E of an observer. A concave lens of focal length f (/_D) is placed near to the eye and image of the object is viewed. Now the lens is moved towards the object O, away from the eye. (a) Show that the angle subtended by the image at the eye first decreases and then increases as the lens is moved away from the eye. (b) Find the distance of the lens from the object when the apparent size of image is smallest.

Two plane mirrors are placed parallel to each other at a distance L apart . A point object O is placed between them, at a distance L/3 from one mirror . Both mirrors form multiple images. The distance between any 'two images cannot be
