Question

If we want infinite number of images what will be the angle between two mirrors

Answer 1

Explanation:

When the angle between the two mirrors is 180 degree they together act like a single mirror so that only one image is visible. ... If the angle between the mirrors is finally decreased to zero, infinite images are expected to be formed. Place both the mirrors vertically with 180 degree angle between the them.

Answer 2

$If \: we \: want \: infinite \\ number \: of \: images, \\ then \: 0 {}^{o} \: will \: \\ be \: the \: angle \: \\ between \: two \: mirrors$
