So if I had two plane mirrors(30 cm square) at an angle of 45 degrees to each other with one edge of each mirror touching the other. There would be 7 images. What if these mirrors were put into space. Where the line where they are touching is the z axis, fro z =0cm to z=30cm and have one mirror at y = 0, the xz plane and the other mirror at y = x, 45 degrees from the xz plane. If an object were place at (15,5,15). Where are the images located.
