Find the region on Y-axis in which reflected rays are present. Object is at A (2, 0) and MN is a plane mirror, as shown in Fig.

Open in App

Solution

The image of point A in the mirror is at $A^{'} (6, 0) .$

$a^{'} M$ and extend to cut Y-axis at M'

(Ray originating from A which strikes the mirror at M gets reflected as the ray MM' which appears to come from A'

$A^{'} N$ and extend to cut Y-axis at N' (Ray originating from A which strikes the mirror at N gets reflected as the ray $N N^{'}$ which appears to come from A')
From geometry $M^{'} = (o, 6)$
$N^{'} = (0, 9)$
M′N′ is the region on Y-axis in which reflected rays are present.
