When a concave mirror is placed facing the sun, the sun's rays converge to a point 10 cm from the mirror. Now if you place a 2 cm long candle flame 20 cm away on the principal axis of the mirror, where would you place a screen to obtain the image of the candle? What would be the size of the image? Draw a ray diagram to justify your answer.
