1. The problem statement, all variables and given/known data Two parallel mirrors are separated by a distance of d = 4 meter. A point object is placed at a position a = 0.4 meter from the mirror 1. How deep is the second image of the object in the mirror 1? How deep is the third image of the object in the mirror 1? http://i.imgur.com/qvb5m.png 2. Relevant equations 3. The attempt at a solution I found the distance of the second image to be 7.6m. Since the first image reflected on the 2nd mirror would be a distance 3.6m away, I added the distance between the second and first mirror to that distance to find the second image on the 1st mirror. I don't know how to find the 3rd image. There was a problem like this in my class, but the object was evenly spaced between the mirrors.
