virtual and erect image?

a) Concave lens c) Convex lens

b) Lens made by plane mirror d) None of these​

Answer 1

Answer:

(b) convex lens

is the correct answer

Answer 2

The answer is a) Convex lens, when the object is placed between the centre of curvature and the focal point of a convex lens, a virtual, erect, upright and magnified image is obtained on the same side of the object, hence it is used in making magnifying glasses and in the treatment of hyperopia. A convex lens can also be used to obtain real and inverted images when the object is placed at or beyond the focus.
