When a concave mirror is placed facing the sun, the sun's rays converge to a point 10cm from the mirror. Now, an erect, 2-cm-long pin is placed 15cm away on the principal axis of the mirror. If you want to get the image of the pin on a card, where would you place the card? What would be the nature and height of the image?



Obj should be placed at centre of curvature so the img would be formed at centre of curvature . the img size would be same size of the obj and it is real and inverted
guess this helps you
