you are setting up a laser show in the physical science lab. the laser is 40 feet from a corner of the lab and is aimed at a mirror on the adjoining wall. the mirror is the same height as the laser and is positioned as shown in the diagram. the laser beam travels along a path given by y = 4/3|x-30|. after the laser beam is reflected by the mirror, where will it hit the third wall?
+36915 We know angle of incidence = angle of reflection, but we'll ned the diagram of the room to find the third wall strike point !
