Two large plane mirrors $PM$ and $PN$ are arrange as shown. The length of the part of large screen $SS'$ in which two images of the object placed at $P$ can be seen is $x$ (in m). Find the value $\sqrt{3} x.$

Answer:

2.00

Solution:

The normals for the mirror PM is PS' and the normal to the mirror PN is PS. From the geometry of the figure it can be seen that ${SS}^{'} = x = \frac{2}{\sqrt{3}}$ .

So, $\sqrt{3} x = 2$
