In questions 1 and 2, two statements are given, one labelled Assertion (A) and the other labelled Reason (R). Select the correct option from those given below with regard to these statements. (a) Both A and R are true, and R is the correct explanation of the assertion. (b) Both A and R are true, and 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.Assertion (A):
(1) A negative sign in the value of the magnification produced by a thin convex lens indicates that the image is real. Reason (R): Height of the image and the object is taken as negative and positive, respectively.
(2) Assertion(A); A concave lens of very short focal length causes higher divergence than the one with a longer focal length. Reason (R): The degree of convergence or divergence of light rays achieved by a lens is expressed in terms of its power.
