Suppose you have three concave mirrors A, B, C of focal lengths 10 cm, 15 cm and 20 cm. For each of these concave mirrors, you perform the experiment of image formation for three values of object distance of 10 cm, 20 cm and 30 cm. Answer the following reasons. (a) Identify the mirror/mirrors with linear magnification - 1. (b) Out of the three mirrors, identify the mirror which would be preferred to be used for shaving purposes/makeup. (c ) For the mirror B, draw ray diagram for image formation for object distance 10 cm and 20 cm.
