Aim: Observing the types of image and measuring the object distance and image distance from the mirror. Materials Required: A candle, paper, concave mirror, V-stand, measuring tape. Procedure: Place the concave mirror on V-stand, arrange a candle and a meter scale as shown in figure. Keep the candle at different distances from the mirror along the axis and by moving the paper, find the position where you get the sharp image on paper. What do you infer from the experiment which you did to measure the object distance and image distance?

For a concave mirror, type and size of the image formed for different object distances can be summarised as, Position of the object Position of the image Enlarged/ diminished Erect/ inverted Real/ virtual At infinity At focus Highly diminished Inverted Real Between infinity and centre of curvature Between centre of curvature and focus Diminished Inverted Real At centre of curvature At centre of curvature Same sized Inverted Real Between centre of curvature and focus Between infinity and centre of curvature Enlarged Inverted Real At focus At infinity Highly enlarged Inverted Real Between focus and pole Behind the mirror Enlarged Erect Virtual And for a convex mirror, type and size of the image formed for different object distances can be summarised as, Position of the object Position of the object Enlarged/ diminished Erect/ inverted Real/ virtual At infinity At focus (behind the mirror) Highly diminished Erect Virtual Between infinity and mirror Between mirror and focus (behind the mirror) Diminished Erect Virtual
