Question

Which of the following lenses would you prefer to use while reading small letters found in a dictionary?

• A. A convex lens of focal length 50 cm.
• B. A concave lens of focal length 50 cm.
• C. A convex lens of focal length 5 cm.
• D. A concave lens of focal length 5 cm.

Answer 1

The Correct Option is C

A convex mirror consistently produces a virtual, erect image that is smaller than the object. A plane mirror, in contrast, always yields a virtual, erect image of the same size as the object. Consequently, the mirror in question could be either plane or convex.
