A light ray coming along the line `3x+4y=5` gets reflected from the line `a x+b y=1` and goes along the line `5x-12 y=10.` Then, (A) `a=(64)/(115), b=(112)/(15)` (B) `a=(14)/(15), b=-8/(115)` (C) `a=(64)/(115), b=-8/(115)` (D) `a=(64)/(15), b=(14)/(15)`

The incident ray is along the line 3x-4y-3=0 and the reflected ray is along the line 24 x+7y+5=0. Find the equation of mirrors.

Show that the reflection of the line a x+b y+c=0 on the line x+y+1=0 is the line b+a y+(a+b-c)=0 where a!=bdot

If a ray of light incident along the line 3x+(5-4sqrt(2))y=15 gets reflected from the hyperbola (x^2)/(16)-(y^2)/9=1 , then its reflected ray goes along the line. xsqrt(2)-y+5=0 (b) sqrt(2)y-x+5=0 sqrt(2)y-x-5=0 (d) none of these

The sides of a rhombus are parallel to the lines x+y-1=0 and 7x-y-5=0. It is given that the diagonals of the rhombus intersect at (1, 3) and one vertex, A of the rhombus lies on the line y=2x . Then the coordinates of vertex A are (8/5,(16)/5) (b) (7/(15),(14)/(15)) (6/5,(12)/5) (d) (4/(15),8/(15))

A ray of light passing through the point A(2, 3) reflected at a point B on line x + y = 0 and then passes through (5, 3). Then the coordinates of B are

Show that the lines (x-3)/(2)=(y-5)/(-1)=(z+7)/(4) and (x-15)/(4)=(y+12)/(-2)=(z-8)/(8) are parallel.

(2)/(x)-(3)/(y)=15,(8)/(x)+(5)/(y)=77
