Problem
A ray of light comes along the line L=0 and strikes the plane mirror kept along the plane P=0 at B . A(2,1,6) is a point on the line L=0 whose image about P=0 is A′ . It is given that L=0 is 3x−2=4y−1=5z−6 and P=0 is x+y−2z=3 . If L1=0 is the reflected ray, then its equation is
(1) \frac{x+10}{4} = \frac{y-5}{4} = \frac{z+2}{3}
(2) \frac{x+10}{3} = \frac{y+15}{5} = \frac{z+14}{5}
(3) \frac{x+10}{4} = \frac{y+15}{5} = \frac{z+14}{3}
(4) None of the above
