Question

Assertion(A): property of converging of a convergent lens does not remain same in all media.
reason(R): property of all lens whether the ray is diverging or converging is independent of the surrounding medium.

(a) both A and R are true, and R is the correct explanation of A.
(b) both A and R are true, but R is not the correct explanation of the assertion.
(c) A is true, but R is false.
(d) A is false, but R is true.

please answer fast​

Answer 1

C) a is false r is true
Thank me later☺️

Answer 2

(c) A is true, but R is false is the correct answer.

• The property of lens depends on the refractive index of medium which surrounds the lens.
• This is due to the reason that light bends as per movement from denser to rarer medium or vice versa.
• Thus change in bending of light changes the converging or diverging property of the lens.
