Question

The smaller the focus of a convex lens, more its magnifying capacity, so why don't we use magnifying glasses with very small focal length?

• A. They are difficult to manufacture.
• B. The image will be too big for our liking.
• C. One would have to hold the magnifying glass to close to the object.
• D. They would be too heavy.

Answer 1

The correct option is C

One would have to hold the magnifying glass to close to the object.

One would have to hold the magnifying glass too close to the object to get the required magnified and erect virtual image.
