Question

The number of images formed by two plane mirrors inclined at an angle ${60}^{\circ }$ of an object placed symmetrically between mirrors is

• A. 5
• B. infinite
• C. 6
• D. 7

Answer 1

The correct option is A 5

The number of images formed by two plane mirrors inclined at an angle ${60}^{\circ }$ when an object is placed symmetrically is
$N=\frac{{360}^{\circ }}{angle}-1$
$N=\frac{{360}^{\circ }}{{60}^{\circ }}-1=5$, where N is the number of images.
