Magnification produced by a concave mirror
WebConcave mirrors are also used in reflecting telescopes. Concave mirrors are used to form optical cavities, which are important in the construction of laser. For concentrating … WebRay diagrams can be used to determine the image location, size, orientation and type of image formed of objects when placed at a given location in front of a concave mirror. The use of these diagrams was demonstrated earlier in Lesson 3.Ray diagrams provide useful information about object-image relationships, yet fail to provide the information in a …
