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 O X , respectively. A ray of light from the source strikes the mirror and is reflected. If the direction ratios of the normal to the plane are 1,-1,1, then find the D C s of the reflected ray.

A point source of light is placed in front of a plane mirror.

A ray of light incident along nirmole to the mirror to the mirror ____ its path.

A ray of light is sent through the point P(1,2,3) and is reflected on the XY plane. If the reflected ray passes through the point Q(3,2,5) then the equation of the reflected ray is

A pencil of light rays falls on a plane mirror and forms a real image, so the incident rays are

A ray of light coming from the point (1,2) is reflected at a point A on the x-axis and it passes through the point (5,3). Find the co-ordinates of the point A.

A ray of light is incidenting normally on a plane mirror. The angle of reflection will be
