(b) concave
(c) convex
(d) either plane or convex

​

Answer 1

Answer:

erect image always appears in convex mirror.

Answer 2

The mirror is likely to be either plane or convex mirror (option-d).

• A plane mirror has a plane smooth surface. It always forms an erect image of an object., independent of the distance of the object.
• A concave mirror has a bludged-in curved surface. It forms both erect and inverted images of an object and this depends on where the object is placed.
• A convex mirror has a bludged-out curved surface. It always forms an erect image of an object and this does not depend on the position of the object.
