A student has obtained a magnified image of a flame on a screen using a convex lens. To draw the corresponding ray diagram to show the image formation, which of the following two rays whose paths after refraction are shown, should he select ?
(A) I and II
(B) II and III
(C) III and IV
(D) I and III
A convex lens converges the refracting ray. Therefore, rays I and III represent the path of the refracting ray from a convex lens(converging lens). As rays II and IV show the refracting ray being diverged, the ray diagrams are incorrect.
Hence, the correct option is D.
