The nature, position and size of the image formed by a concave mirror depends on the
position of the object in relation to points P, F and C. The image formed is real for
some positions of the object. It is found to be a virtual image for a certain other
position. The image is either magnified, reduced or has the same size, depending on
the position of the object.
(a) It is desired to obtain an erect image of an object, using a concave mirror of focal
length 20 cm.
18.(i) What should be the range of distance of the object from the mirror?
18.(ii) Will the image be bigger or smaller than the object?
18.(iii) Draw a ray diagram to show the image formation in this case
