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

      f= -10cm (since the image is formed at the focus)
      Now u= – 20cm, i,e. the candle flame is at C
      Therefore, the image would form at C and would be of the same size. Ray diagram :
