    If two adjacent walls and the ceiling of a rectangular room are mirror surfaced, then how many images of himself, a man can see?

    A)  3                                

    B)  5

    C)  6                                

    D)  9

    Correct Answer: C

    Solution :

    Total number of images formed = 6 Because with an object placed between two plane mirrors inclined at an angle of \[{{90}^{o}},\] one image is produced due to each mirror and one due to their combination. With three images right angles to each other, one image is produced by each plane mirror and one by each of the three pairs of combination of two mirrors each.
