Web2 Answers. Sorted by: 1. In the case of the lens, you see that the the light rays first go through the lens, then the focal plane, and then through the plane of the real image. So if you're standing in the focal plane, the photons hit you before they converge in the real image: you're supposed to stand on the far right side!
