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.
The coordinates of B are
a. (5,10,6)
b. (10,15,11)
c. (−10,−15,−14)
d. None of these
