Which of the following graph represents relation between the image position (v) and object position (u) from the concave lens.

The graph between the image distance (v ) and object distance (u) from the convex lens is

Which of the following form(s) a virtual and erect image for all positions of the object? (1) Convex lens (2) Concave lens (3) Convex mirror (4) Concave mirror

Which of the following graph represents v/f vs u/f graph for a virtual erect image by a diverging lens?

Which of the following graph represents v/f vs u/f graph for a virtual erect image by a diverging lens?

Which of the following graph represents v/f vs u/f graph for a virtual erect image by a diverging lens?

For a concave lens of focal length f, the relation between object and image distance u and v, respectively, from its pole can best be represented by (u = v is the reference line) :

Giving reasons, the 'signs' (positive or negative) which can be given to the following : (a) object distance (b) image distances ( c) image distances (u) for a concave mirror or convex mirror (v) for a concave mirror (v) for a convex mirror
