1.	You are given a concave mirror of focal length 20 cm and a candle. Where will you hold the candle to form a virtual, erect and magnified image of the candle flame ? Draw the necessary ray diagram.
Answer» Solution :Here, `f= - 20 CM`. To form a virtual, ERECT and magnified image of candle flame, the flame is to be held at a distance less than `20 cm` from the concave mirror, in front of the mirror. In the ray diagram , A'B' is virtual, erect and magnified image of object AB held in front of the concave mirror at a distance less than `PF=20cm`.
