We are going to fire a laser at a position of one meter to the left of the left of the bottom right corner of the a box. Assume the sides of the box to be perfect mirrors. At what angle do we need to point the laser, as measured from the positive x direction (theta = 0), in order to have the light pulse arrive back to the starting position? How long did the light take to leave and return? Assume that the box is in a vacuum. It is not 90 degrees. You must bounce the laser off of more than one wall.
