Plot the graphs of `|(1)/(V)|` vs `|(1)/(u)|` where v is image distance and u is object distance for the conditions given below:

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

The focal f to a mirror is given by (1)/(f) = (1)/(u) + (1)/(v) where u and v represent object and image distance respectively then

The graph showing correctly the variation of image distance (v) as a function of object distance (u) in case of a concave mirror is

The graph showing correctly the variation of image distance (v) as a function of object distance (u) in case of a concave mirror is

In an experiment to measure the focal length of a convex lens , the data for image distances (v) for difference object distance (u) are plotted to obtain the three graphs of (1) v against u , (2) (1)/(v) against (1)/(u) and (3) u + v against u . It possible to find the focal length directly , without any further calculations , from which of these graphs ?

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

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