Question

An object of height \( h \) is placed midway between \( f \) and \( 2f \) in front of a biconvex lens. A real inverted image is captured on a screen placed a little beyond \( 2f \) on the other side of the lens. If the whole arrangement is immersed in water without disturbing the object, lens and the screen positions, then the new image formed will be

• A. Magnified virtual erect image on the same side of the lens where the object is placed
• B. Magnified real inverted image on the same side of the lens where the object is placed
• C. Diminished real inverted image on the other side of the lens between \( f \) and \( 2f \)
• D. Magnified real inverted image on the other side of the lens beyond \( 2f \)

Hint:

When a convex lens is immersed in water, its relative refractive index decreases, so its power decreases and focal length increases.

Answer 1

The Correct Option is A
