Consider the following statements: If the lens is immersed in a medium...
Explanation:
Statement I: If the lens is immersed in a medium having a refractive index equal to that of the lens, then it behaves as a concave lens.
This statement is incorrect. The behavior of a lens does not depend on the refractive index of the medium in which it is immersed. It depends on the shape and curvature of the lens itself. A concave lens will always behave as a concave lens, regardless of the refractive index of the medium.
Statement II: If the lens is immersed in a medium having a refractive index equal to that of the lens, then it becomes invisible.
This statement is incorrect. The visibility of an object does not depend on the refractive index of the medium in which it is immersed. It depends on the interaction of light with the object and the medium. Even if the refractive index of the medium is equal to that of the lens, the lens will still be visible.
Statement III: If the lens is immersed in a medium having a refractive index equal to that of the lens, then its focal length becomes half.
This statement is incorrect. The focal length of a lens is determined by its shape and curvature, not by the refractive index of the medium in which it is immersed. The refractive index of the medium affects the speed of light, but it does not directly affect the focal length of the lens.
Therefore, only Statement II is correct. The correct option is (b) Only II is correct.
