A refracting surface is represented by the equation `x^(2)+y^(2) = a^(2)`. A ray travelling in negative x-directed towards positive y-direction after reflection from the surface at point P. Then co-ordinates of point P are

The cross-section of a reflecting surface is represented by the equation x^2 + y^2 = R^2 as shown in the figure. A ray travelling in the positive x direction is directed toward positive y direction after reflection from the surface at point M. The coordinate of the point Mon the reflecting surface is
