Answer 2

Answer:

A boy 2m tall stands 40cm in front of a mirror. He sees an erect image,1 m high. The mirror is​ Convex or diverging mirror.

Explanation:

From the question, we can infer that the image of the boy formed in the mirror has the following characteristics: -

1.The image is diminished in size.

2. It is erect.

3.It is virtual ( erect images are always virtual)

4. It is behind the mirror.

Such an image is formed in a convex mirror when the object is between infinity and pole of the mirror. The ray diagram is shown in the figure attached.

Convex mirrors are used at road intersections to give a smaller, erect image of a larger area at the intersection.
