Question

A student obtained a sharp image of the grill of a window on a screen, using a convex lens. For getting better results, the teacher suggested focusing on a distant tree instead of the grill. In which the direction should the lens be moved for this purpose?​

Answer 1

Answer:

Towards the screen

Explanation:

When the image distance increases, object distance decreases. Thus, distance between the mirror and screen will decrease. So, the mirror should be moved towards the screen. When the image distance increases, object distance decreases.
