Problem 13

A ray of light incident at the point \((3,1)\) gets reflected from the tangent at \((0,1)\) to the cirde \(x^{2}+y^{2}=1\). The reflected ray touches the circle. The equation of the line along which the incident ray moves is: (a) \(3 x+4 y-13=0\) (b) \(4 x-3 y-13=0\) (c) \(3 x-4 y+13=0\) (d) \(4 x-3 y-10=0\)

Expert verified

The equation of the line along which the incident ray moves is \(3x+4y-13=0\).
