Question: Suppose that we replace the parabolic mirror of Problem 20 by a spherical mirror. Although the mirror has no focus, we can show the existence

Suppose that we replace the parabolic mirror of Problem 20 by a spherical mirror. Although the mirror has no focus, we can show the existence of an approximate focus. In the figure, C is a semicircle with center . A ray of light coming in toward the mirror parallel to the axis along the line PQ will be reflected to the point R on the axis so that ∠PQR = ∠OQR (the angle of incidence is equal to the angle of reflection). What happens to the point R as P is taken closer and closer to the axis?
