Question

Assertion (A): Property of converging of convergent lens does not remain same for all media. Reason (R): Property of lens whether the ray is diverging or conversing is independent of thesurrounding medium

Answer 1

Answer:

A is false. B is right. Converging property of lens is its own property.

Answer 2

• The property of the lens, whether they would be converging and diverging, depends on the surrounding medium.
• The lens's focal length is affected by the refractive index of the lens wrt to the medium.
• So, as the surrounding medium would change, the lens's converging and diverging powers would vary.
• If the refractive index of a lens is less than the refractive index of the medium, a diverging lens will act as a converging lens and vice versa.
• While the property of the lens, whether the ray is diverging or converging, is dependent on the surrounding medium.

Hence, the assertion is true, and the reason is false.
