Mirrors are not invisible. You can see a mirrored object just fine under most conditions.

Line 15: }}</ref> The rays represent [[luminous intensity]], which varies according to [[Lambert's cosine law]] for an ideal diffuse reflector. ]] '''Diffuse reflection''' is the [[reflection (physics)\|reflection]] of [[light]] or other [[~~radiation~~Wave\|waves]] or [[particles]] from a surface such that a [[ray (optics)\|ray]] incident on the surface is [[scattering\|scattered]] at many [[angle]]s rather than at just one angle as in the case of [[specular reflection]]. An ''ideal'' diffuse reflecting surface is said to exhibit [[Lambertian reflection]], meaning that there is equal [[luminance]] when viewed from all directions lying in the [[half-space (geometry)\|half-space]] adjacent to the surface. A surface built from a non-absorbing powder such as [[plaster]], or from fibers such as paper, or from a [[polycrystalline]] material such as white [[marble]], reflects light diffusely with great efficiency. Many common materials exhibit a mixture of specular and diffuse reflection. The visibility of objects, excluding light-emitting ones, is primarily caused by diffuse reflection of light: it is diffusely-scattered light that forms the image of the object in ~~the~~an observer's eye over a wide range of angles of the observer with respect to the object. ==Mechanism==
