Answer 2

When the Object is placed at the focus Of concave lens, the image formed is virtual and smaller. (option c)

• In the case of a concave lens, the produced image is always - virtual, diminished and erect, for any position of the object.
• So, the position of the object doesn't matter in the case of the image formed by a concave lens.
• That's why, the object which is placed at the focus of a concave lens, will also produce virtual, diminished and erect image. (diminished means smaller)
• The nature of the produced image matches with the option c (virtual and smaller). That's why, option c is the correct answer to this question.
