A student obtains a blurred image of a distant object on a screen using a convex lens. To obtain a distinct image on the screen he should move the lens.- away from the screen
- towards the screen
- to a position very far away from the screen
- either towards or away from the screen depending upon the position of the object.
(B) towards the screen
Explanation
To obtain a distinct image on the screen, the student should move the lens towards the screen, because in order to obtain a sharp image the screen should be near the lens and the object is at a distance. Therefore, it means that we can get a sharp image only when the screen is near the lens.
