When an Object is Placed 10 Cm in Front of Lens A, the Image is Real, Inverted, Magnified and Formed at a Great Distance. When the Same Object is Placed 10 Cm in Front of Lens B, The Image Formed is Real, Inverted and Same Size as the Object. What is the Nature of Lens B? - Science

When an object is placed 10 cm in front of lens A, the image is real, inverted, magnified and formed at a great distance. When the same object is placed 10 cm in front of lens B, the image formed is real, inverted and same size as the object. 

 What is the nature of lens B?

Solution

 Lens B is a converging (convex) lens as only a converging lens forms a real image.

Concept: Concave Lens
