. Statement 1: Paraxial rays are always parallel to the axis of a mirror or lens.
Statement 2: A parallel beam close to principal axis converges at the focal point.
Options:
Answer:
D
Solution:
Statement-1 is false: paraxial rays are rays close to the principal axis making small angles with it, not necessarily parallel to it. Statement-2 is true: a parallel beam close to the principal axis converges at the focal point. Hence (D).
