The reversed-image mirror

Plan2,Ljus,Fysik,Helt sinnes
You see yourself in a mirror because it reflects light. A bent mirror reflects light towards a specific point. If you can find the point of focus, the image will be non-reversed. Can you find this point?

The curved mirror reflects the light in a different way than a flat mirror. The light reflected in the curved mirror merges at one point, the so-called focal point. Within the focal point, the image is reversed. At the centre of the focal point, all the reflective rays meet the eye and the image becomes impossible to discern. Beyond the focal point, light is reflected from the right to the left side, and from the left to the right side. By walking back and forth at about two metres from the mirror, you will be able to find the focal point.
