Question

what would be the number of images seen when two plane mirrors are placed inclined at an angle of 36 degree to each other

Answer 1

\\
$number \: of \: images = \frac{360}{ \alpha } - 1 \\ here \: \alpha \: is \: angle \: between \: two \: mirrors \\ \frac{360}{36} - 1 \\ 10 - 1 = 9 \\ hence \: 9 \: images \: will \: be \: \: seen$
