The graph between `(1)/(v)` and `(1)/(u)` for a concave mirror looks like.

For a concave mirrorr, if real image is formed the graph between (1)/(u) and (1)/(v) is of the form

For a concave mirrorr, if real image is formed the graph between (1)/(u) and (1)/(v) is of the form

The graph between u and v for a convex mirrorr is

The graph between u and v for a convex mirrorr is

Nature of the graph between 1//u and 1//v for a convex lens, where u is the distance of the object and v is that of image is

The graph betwene P and V at constant temperature should look like
