A ray of light is sent along the line x+y=1 after being reflected from the line y_x=1 it is again reflected from the line y=0 then the equation of the line representing the ray after second reflection may be given as?
Here, is a diagram of the whole thing happening,
Light after coming by the pathway of
Now, clearly, slope of the straight line
So,let the equation of the reflected pathway is
And, that of the straight line,to which it will be parallel is
Now,if the distance between them is
So,the equation of straight line,alomg which the reflected ray will go, will be
