Statement-I: If a parallel paraxial beam of light were incident on a concave mirror, making some angle with the principal axis, the reflected rays would converge at a point in focal plane.
Statement-II: Power(P) of concave mirror is positive even though focal length(f) is negative.
In the light of the above statements, choose the most appropriate answer from the options given below.
Solution:
Statement I is a standard result of paraxial ray optics. For Statement II, power of a mirror is given by \(P = -1/f\). Since \(f\) is negative for a concave mirror, \(P\) is positive. Thus, both statements are correct.
