1.	a convex lens of focal length 10 cm is placed at a distance of 12cm from a wall. How far from the lens should an object be placed so as to form its real image on the wall?
Answer» Answer: This means that the distance of image from the CONVEX LENS or image distance will be 12 cm. Since a real image is fomred on the RIGHT side of the lens, so this image distance will be positive. THUS, the obect should be place at a distance of 60 cm in front of the convex lens. Explanation: please mark me as brain
