A light ray emerging from the point source placed at `P(1,3)` is reflected at a point Q in the axis of x. If the reflected ray passes through the point `R(6, 7)`, then the abscissa of Q is:

A light ray emerging from the point source placed at P(2,3) is reflected at a point Q on the y-axis.It then passes through the point R(5,10). The coordinates of Q are (0,3)(b)(0,2)(0,5)(d) none of these

A ray of light is sent along the line which passes through the point (2,3). The ray is reflected from the point P on x-axis.If the reflected ray passes through the point (6,4), then the co-ordinates of P are

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 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 ray of light passing through the point P(1,2) reflects on the x-axis at the point A and the reflected ray passes through the point Q(5,3). Find the coordinates of the point A

A ray of light passing through the point (1,2) reflects on the xaxis at point A and the reflected ray passes through the point (5,3) . Find the coordinates of A.

A ray of light passing through the point (1,2) reflects on the x-axis at point A and the reflected ray passes through the point (5,3) Find the co-ordinates of A.

A light beam 2x+y+1=0 emanating from the point (-1,1) gets reflected from the straight line x+y+1=0 then reflected ray passes through
