Answer 1

The lower half of a concave mirror is covered with Opaque material. Then the intensity of the image will be reduced.

Explanation:

Because the law of reflection applies to all points on the remaining portion of the mirror, the image will be that of the entire object. However, because the size of the reflecting surface has been lowered, the picture intensity will be low.
