A mirror and source of light are situated at the origin O and a point on OX respectively. A ray of light from the source strikes the mirror and is reflected. If the DRs of the normal to the plane of mirror are `1,-1,1,` then DCs for the reflacted ray are :

A mirror and a source of light are situated at the origin O and at a point on OX, respectively. A ray of light from the sources strikes the mirror and is reflected. If the direction ratios of the normal to the plane are 1, -1, 1, then find the DCs of the reflected ray.
