Talk:Plane mirror

Virtual images, functions of plane mirrors
When I view the article today, a sentence reads, "The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting." This contains a few notions that are misleading as written. First, the image formed by a plane mirror is not necessarily virtual. Yes, in ordinary circumstances, i.e., not from the perspective of an optical engineer but someone (for example) seeing their image in a bathroom mirror, your image is indeed virtual. However, plane mirrors are routinely used in the design of products to relay an image from one part of the system to another - such as when an optical design is "folded" - and this frequently results in real images, not just virtual ones. Second, the embedded definition of virtual image is suspect. A virtual image is an image that is not physically accessible, whereas a real image is an image that IS physically accessible. Anyone care to elaborate or repair this article? Gregg Favalora (talk) 13:06, 2 April 2012 (UTC)


 * @Gregg Favalora i think image formed by plane mirror is virtual, because it dont intersect actually anywhere in reality Harsh Kumar.s (talk) 12:00, 13 November 2022 (UTC)
