(ii) a magnified virtual image?
(iii) a diminished real image?
(iv) an image of same size as the object​

Answer 1

Step-by-step explanation:

1. 35 cm

1. 35 cm2.a magnified virtual image?

Answer 2

Answer:

1) A magnified real image = when the object is placed at a distance of 20cm from the mirror i.e. between focus and center of curvature.

2) A magnified virtual image = When the object is placed at a distance 10 cm from the mirror i.e., within its focus.

3) A diminished real image = When the object is placed at a distance of 35 cm from the mirror i.e., beyond the center of curvature.

4) An image of same size as the object = When the object is placed at a distance of 30 cm from the mirror i.e., at center of the curvature.
