Answer
Exam answer
(d) Less than or equal to 15 cm.
Explanation
A concave lens forms its virtual image between the optical centre and principal focus, so | v | cannot exceed | f | = 15 cm.

Identify the type of lens used.2026What would be the magnification (more than 1 / less than 1 / equal to 1) if the object is placed between F and 2F of the above lens?2026An object placed in front of a convex lens, forms an image of same size on a screen. Moving the object 12 cm closer to the lens results in the formation of a real image which is three times the size of the object. Calculate the focal length of the lens.2026For a real image formed by a convex lens, the ratio of I : O = 2 : 5, then the object is:
(I is the height of the image and O is the height of the object)
(a) between O and F
(b) beyond 2F
(c) at F
(d) between F and 2F2025 An object is placed at 2F position of a convex lens. Draw a ray diagram showing the formation of the image.2025How will the size of the image change if we, ONLY replace the lens in the above arrangement with another lens of a greater focal length?2025
