A ray diagram that shows the position and the magnification of the image formed by a concave mirror. The concave mirror differs greatly depending on whether the object is inside the focus of the concave mirror.
Le centre c (centre de la sphère), le sommet s (point d'intersection entre le miroir et l'axe optique) rayon de courbure r (rayon de la sphère).
It might help you to remember this if you think that when you look in a concave mirror, it. Dessiner des normales à chacun des points d'incidence. Unlike convex mirrors, the image formed by a concave mirror shows different image types depending on. If the object is in the focus of the mirror:
Dans les formules d'optique, le rayon de courbure est une grandeur algébrique.

Miroir projectors make it easier than ever to share your world, whether for. Dans un miroir concave, il suffit de dessiner des rayons de courbure, car, par définition, un rayon arrive toujours perpendiculairement à la surface d'un miroir courbe.
A concave mirror is a spherical mirror, which has a reflecting surface, dented inwards.
