Suppose that the lower half of the concave mirror’s reflecting surface is covered with an opaque material. What effect will this have on the image of an object placed in front of the mirror?

Question

Suppose that the lower half of the concave mirror’s reflecting surface is covered with an opaque material. What effect will this have on the image of an object placed in front of the mirror? (A) Magnification will become less (B) Image will show only half of the object (C) Intensity of image will become less (D) No change in any aspect of the image

The remaining part of the mirror will reflect the total image of the object. However, as the area of the reflecting surface has been reduced, the intensity of the image will be low (in this case half).

Q. Suppose that the lower half of the concave mirror’s reflecting surface is covered with an opaque material. What effect will this have on the image of an object placed in front of the mirror?

Magnification will become less

Image will show only half of the object

Intensity of image will become less

No change in any aspect of the image
