Question

Suppose that one half of a concave mirror reflecting surface is covered with nonreflecting suit. What effect will this have on the image of an object placed infront of mirror?

Answer 1

Blocking one half will make the mirror look like a semi-circle. It won’t affect the nature of image. The image will be less brighter than that formed by a full mirror. It is because image will be formed by the rays reflected from the one half only.
