    If two mirrors are kept at 60° to each other, then the number of images formed by them is   AIEEE  Solved  Paper-2002

    A) 5    

    B)                                          6                                

    C)           7                                

    D)           8

    Correct Answer: A

    Solution :

    Number of images, \[n=\frac{{{360}^{o}}}{\theta }-1\] where, \[\theta \] is angle between mirrors.              Thus,                        \[\theta ={{60}^{o}}\]                    (given)              So, number of images                 \[n=\frac{{{360}^{o}}}{{{60}^{o}}}-1=5\]
