Problem
A spherical mirror is used to form images of small objects kept on its principal axis. Answer the following questions.
(a) Write the relation connecting magnification with the heights of the image and the object.
(b) The magnification produced by a mirror is positive. What does this signify about (i) the nature of the image, and (ii) its orientation with respect to the object? Explain briefly.
(c) A student notes the magnification produced by the same mirror as –1.5. State, with reason, whether the image is real or virtual and erect or inverted when the magnification has this value.
