Equation of lineBABAisx+y=1x+y=1. Find a unit vector along the reflected rayACAC. Share with your friends Share 0 Ved Prakash Lakhera answered this The slope of the line AB is: y=-x+1slope = m=-1or tanα=-1or α = -π4The equation of line AC is given by; x cosπ4i^ + y sinπ4j˙ or x2i^ + y2j^The unit vector in the direction of AC ray of reflection; n^ = x2i^ + y2j^x2+y22 =xx2+y2i^+yx2+y2j^or n^ =xx2+y2i^+yx2+y2j^ 0 View Full Answer
