Question

Could you get an image on the screen for every object distance with a convex lens?

Answer 1

no you can't get an image of the object is placed before or at Focus of the lens then the image will be virtual

Answer 2

Answer:

No, if an object is placed between the focus and pole of the lens, then a virtual image is obtained which cannot be formed on the screen.

Explanation:

Convex Lens:

• It is a converging lens.
• For object distances greater than the focus of the lens, the lens acts as a converging lens and hence a real image is formed, which can be produced on a screen.
• For object distances less than the focus, the lens acts as a diverging lens and hence forms a virtual image.

For object distances less than the focus of the lens an image cannot be formed on the screen.
