Which of the following graphs is the magnification of a real image against the distance from the focus of a concave mirror?

A graph is plotted between angle of deviation (δ) and angle of incidence (i) for a prism. The nearly correct graph is

A student measures the focal length of a convex lens by putting an object pin at a distance `u\' from the lens and measuring the distance v of the image pin. The graph between ‘u’and ‘v’ plotted by the student should look like

For a small angled prism, angle of prism A, the angle of minimum deviation (δ) varies with the refractive index of the prism as shown in the graph

A medium shows relation between i and r as shown. If speed of light in the medium is ncthen value of n is

For a concave mirror, if virtual image is formed, thegraph between m and u is of the form

A ray of light travels from a medium of refractive index μ to air. Its angle of incidence in the medium is i, measured from the normal to the boundary, and its angle of deviation is δ. δ is plotted against i which of the following best represents the resulting curve

The distance v of the real image formed by a convex lens is measured for various object distance u. A graph is plotted between v and u, which one of the following graphs is correct

For a convex lens the distance of the object is taken on X-axis and the distance of the image is taken on Y-axis, the nature of the graph so obtained is
