Question

when half of the mirror is covered with a black strip.what happens to the image formed

Answer 1

If it is a plane mirror, then the part of the object that is reflective of the part of the mirror which is not covered with the black strip will be seen as a reflected image.

However, if it is a concave or a convex mirror, then there will not be any change in the real image of the object and the lens will be able to produce a complete image of the object.

However, the brightness or the intensity of the image will be quite reduced. This is because a few rays that are forming the object's image will be hindered due to the presence of a barrier in the name of the black strip. Therefore, there will be a minimization of the intensity of the image formed.

Answer 2

Answer:

no change except for change in intensity
