Question

Assertion (A) : A concave lens of very short focal length causes higher divergence than one with longer focal length.\ Reason (R) : The power of a lens is directly proportional to its focal length.\

Professor PC Thomas Classes · Answer

(c):The concave lens of very short focal length causes a higher divergence than the one with a longer focal length. So, assertion (A) is true.\ The power of lens is inversely proportional to its focal length. So, Reason (R) is false.\
