At the main focus of a concave mirror with a radius of curvature R = 2 m there is a point source of light. A screen perpendicular to the main optical axis of the mirror is placed at a distance L = 10 m from the source. How many times is the illumination in the center of the light spot resulting on the screen greater than the illumination in the same place on the screen created by the source in the absence of a mirror? Neglect the loss of light in the air and during reflection.
