A ray of light comes 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 (x-2)/(3)= (y-1)/(4)= (z-6)/(5) and P =0is x+y-2z=3. The coordinates of A' are |

Answer» `(6, 5, 2)` `""(x_(2)-2)/(1)= (y_(2)-1)/(1)= (z_(2)-6)/(-2)` `""=(-2(2+1-12-3))/(1^(2)+1^(2)+2^(2))=4` `rArr ""(x_(2), y_(2), z_(2))-= (6, 5, -2)`. |
