18, Suppose you have three concave mirror A,B and C of focal lengths 10cm, 15 cm and 20 cm. For each concave mirror you perform the experiment of image formation for three values of object distances of 10 cm, 20 cm and 30 cm. Giving reason answer the following: - For three object distance, identity the mirror/ mirrors which will form an image of magnification -1.
- Out of the three mirrors identify the mirror which would be preferred to be used for shaving purposes/make-up.
- For the mirror B draw ray diagram for image formation for object distances 10 cm and 20 cm.
