Question
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?
-
I and II
-
II and III
-
III and IV
-
I and III
Solution
D.
I and III
The correct option is D.
Convex lens is a converging lens. Therefore, rays I and III represent the path of the refracting ray from a convex lens (converging lens). Figure II and IV show the refracting ray being diverged. So, the ray diagrams are incorrect.
