    Question

    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?
    A Point between optic centre and focus Correct Answer Incorrect Answer
    B Principal focus Correct Answer Incorrect Answer
    C Point between the centre of curvature and focus Correct Answer Incorrect Answer
    D Centre of curvature Correct Answer Incorrect Answer

    Solution

    Principal focus : A ray of light from the object, parallel to the principal axis, after refraction from a convex lens, passes through the principal focus on the other side of the lens. • In case of a concave lens, the ray appears to diverge from the principal focus located on the same side of the lens.
