Section C: Give a short answer to the question given below.
(i) An object of \(8\ cm\) height is placed at a distance of \(22\ cm\) from the optical centre of a concave lens of focal length \(17\ cm\). Calculate (1) image distance and (2) the magnification in this case.
(ii) Compare the values of magnification obtained by a concave lens and a convex lens when both the lenses form virtual images.
(ii) Compare the values of magnification obtained by a concave lens and a convex lens when both the lenses form virtual images.
(i) (1) The image is formed the lens.
The image distance is \(cm\).
(2) The magnification of the lens is .
The formed image is .
(ii) The magnification of the concave lens is always and the magnification of the convex lens is , when both the lenses form virtual images.
