WitrynaThese types of mirrors reflect light inward to one focal point namely focii of the mirror. The image formed by a concave mirror gives different image types depending on the distance between the object and the mirror. Light converges at a point when it strikes and reflects back from the reflecting surface of the concave mirror. WitrynaYes, convex lenses can create both real and virtual images depending on the object placed in front. A convex lens that forms a virtual image can only be used if the object is located between the focal point and the optical centre of Lens. A convex lens with a focal length of 30 cm is used to place a point object 60 cm in front. phoebe nursing facilityWitrynaA convex lens with an object placed closer to it than its focal point _____. forms a real image on the same side of the lens. forms a virtual image on the other side of the lens. cannot form a real image. forms a real image on the other side of the lens. asked by mir. phoebe noyes library old lyme ct

"WitrynaRay Diagrams for Lenses. The image formed by a single lens can be located and sized with three principal rays.
