Type: MCQ-diagram based-Easy-Class 12
Consider a convex lens partially submerged in a liquid with a refractive index equal to that of the lens. Which of the following describes the behavior of the lens in this setup?
A
The lens acts like a plane sheet of glass.
B
The lens continues to converge light strongly.
C
The lens diverges light like a concave lens.
D
The lens becomes opaque and reflects all light.
Correct Answer
Option A
Detailed Explanation
When the refractive index of the lens matches that of the surrounding liquid, the lens effectively disappears and acts like a plane sheet of glass, as the focal length becomes infinite.
