Question
An object is placed at a certain distance from a converging lens. This distance is greater than
twice the focal length of the lens. The principal focus on each side of the lens is marked F and
two rays from the top of the object are shown.
Which statement about the image formed is correct?
(A) The image is diminished and inverted.
(B) The image is diminished and upright.
(C) The image is enlarged and inverted.
(D) The image is enlarged and upright.
▶️Answer/Explanation

Question
The diagram shows two rays of light that have passed from an object through a converging lens.
Which labelled point X or Y is a principal focus of the lens, and how does the size of the image compare with the size of the object?
▶️Answer/Explanation
Answer: A
Explanation: In a converging lens, the principal focus is the point where parallel rays of light converge after passing through the lens. Point X is the principal focus, and the image formed is larger than the object when the object is placed between the focal point and the lens. Therefore, the correct answer is A.
