Question

Answer 1

Since, the tendency of a concave lens is to diverge a parallel beam of light falling on the lens surface, it would show exactly the opposite behaviour if placed in a medium of higher refractive index than the material of the lens.
Thus, the correct option will be one in which a concave lens diverges a parallel beam of a light ray.
