प्रश्न
A 1 cm high object is placed at a distance of 2f from a convex lens. What is the height of the image formed?
उत्तर
The height of the image formed is 1 cm. The reason being, when an object is placed at a distance of 2f from a convex lens, the size of the image formed is equal to the size of the object .
