A ray of light from the object parallel to principal axis of a concave lens, after refraction appears to diverge from which point on the same side of the lens?

Correct option is B

The correct answer is (b) Principal focus.
· A concave lens, also known as a diverging lens, causes parallel rays of light to diverge after passing through the lens.
· These diverging rays appear to emanate from a single point on the same side of the lens as the light source.
· This point is called the principal focus of the concave lens.
· The principal focus is located on the optical axis of the lens, at a distance equal to the focal length from the lens.
· This property of the concave lens is crucial in understanding how it forms virtual, diminished, and upright images of objects.
Information Booster:
· Point between optic centre and focus : This is incorrect because the ray does not appear to diverge from a point between the optic center and the focus.
· Point between the centre of curvature and focus : This is incorrect because the diverging rays do not appear to originate from this point in the context of a concave lens.
· Centre of curvature : This is incorrect because the centre of curvature is related to spherical mirrors, not lenses, and does not apply to the refraction in concave lenses.
