A dentist mirror is a concave mirror. Concave mirrors are curved inward at the center, like the inside of a bowl.

This makes objects appear larger than they actually are.

The mirror reflects light in such a way that the light rays are parallel to each other after reflection. This makes objects appear the same size as they actually are. Cylindrical mirrors are used in some telescopes and microscopes.<\/p>\n<p>A convex mirror is a mirror with a convex surface. The mirror reflects light in such a way that the light rays diverge after reflection. This makes objects appear smaller than they actually are. Convex mirrors are used in some security mirrors and rearview mirrors.<\/p>\n<p>A plane mirror is a flat mirror. The mirror reflects light in such a way that the light rays are reflected back in the same direction that they came from. This makes objects appear the same size as they actually are. Plane mirrors are used in many everyday objects, such as mirrors in bathrooms and bedrooms.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[64],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>A Dentist mirror is a<\/title>\n<meta name=\"description\" content=\"A cylindrical mirror is a mirror with a cylindrical surface.
