Lab on Image formation by mirrors

C$.$ Observers at M and N are looking at an image of the pin in the mirror.

$1.$ Suppose that all but a small portion of the mirror

were covered as shown at right.

How, if at all, would this change affect what the observers at M and N see? Explain.

Determine the region in which an observer must be located in order to see an image of the pin. Discuss your reasoning with your partners.

Would two observers at different locations in this region agree on the approximate location of the image? Explain.

$2.$ Suppose that all but a small portion of the mirror near the center were covered, as shown at right.

Determine the region in which an observer must be located in order to see an image of the pin.

Would two observers at different locations in this region agree on the approximate location of the image? If so$,$ find the approximate image location. If not, explain how you can tell.
