Answer 2

(i) real and enlarged image- Concave mirror

(ii) virtual and enlarged image- Concave mirror

(iii) virtual and diminished image- Convex mirror

(iv) real and diminished image- Convex mirror

Explanation:

• The images which are formed by the convex mirrors are always virtual and diminished.
• The concave mirror does not form or produce a virtual and diminished image.
• A spherical mirror is said to be a convex mirror if its outer side is reflecting.
• A spherical mirror is said to be a concave mirror if its inner side is reflecting.
