Answer 1

The entire image will be visible but the intensity of the image will be reduced

Answer 2

Explanation:

If the plane mirror is covered with a black paper then the complete image of the object will be formed. It does not matter how much portion of the mirror is covered. Only the brightness of the image of the object will be affected.

But the intensity of the image of the object will be reduced. As the reflected rays will be less. More the number of reflected rays, more the intensity will be.
