A plane mirror is placed at the center of a concave mirror having a radius of curvature of 40 m. The plane mirror rotates at the speed of 2600 revolutions per second. Calculate the angle between ray incidents on the plane mirror and then reflected from it after the light has traveled to the concave mirror and back to the plane mirror. Given, speed of the light is 3 x 10^8 m/s.
