Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as: Assertion (A): A hypermetropic person prefers to remove his spectacles, while driving. Reason (R): When a hypermetropic person wearing the spectacles looks at a distant object, the parallel rays from the distant object get converged in front of the retina.

Direction: In the Following Questions, A Statement of Assertion (A) Is Followed by A Statement of Reason (R). Mark The Correct Choice As: Assertion : There exists two angles of incidence for the same magnitude of deviation (except minimum deviation) by a prism kept in air. Reason : In a prism kept in air, a ray is incident on the first surface and emerges out of the second surface. Now if another ray is incident on the second surface (of prism) along the previous emergent ray, then this ray emerges from the first surface along the previous incident ray. This particle is called the principle of reversibility of light.
