NEET 2026 Physics question

In a concave lens, a ray of light emanating from the object parallel to the principal axis of the lens after refraction:

(1)passes through , which is the radius of curvature of the lens.
(2)appears to diverge from the first principal focus.Correct
(3)emerges parallel to the principal axis.
(4)passes through the second principal focus.

Answer: (2)

Solution

A concave (diverging) lens bends a ray parallel to the principal axis away from the axis so that the refracted ray, extended backwards, appears to come from the principal focus on the incident side of the lens (a virtual focus, the image position for an object at infinity). Option (2) describes this (apart from the
