Consider a beam of monochromatic light incident on a flat mirror in such a way that the angle of incidence is 30 degrees. This beam strikes the mirror from a point P at a height of 1.5 meters above a table, forming a reflection angle of 30 degrees. Upon reflection, part of this beam strikes a ruler placed perpendicularly to the mirror's surface, creating a line of reflected light that reaches a point Q at a distance of 2 meters from the point of incidence on the mirror. Based on this setup, answer: (1) Calculate the perpendicular distance from the point of incidence P to the point where the line of light strikes the ruler, knowing that the height of point Q above the table is 1 meter. (2) Analyze the result obtained in light of the concept of image formation in flat mirrors and explain how the property that the distance from the mirror to the image is equal to the distance from the mirror to the object is reflected in your solution.
