The most common use of a concave lens is its use in reading glasses.Following are some uses of concave mirror and lens. We come across a variety of activities on a daily basis which involves their application. Mentioned below are the details of the images that will be formed using the concave lens- Position of the Objectīoth concave mirror and lens are much more useful than those scientific experiments. Let us have a look at the ray diagrams of a concave mirror and understand the variation in the position and nature of the image with respect to the position of the object. The image formed by the concave mirror varies in nature and position because of the placement of the object. Here is the detailed Class 9 ICSE Physics Syllabus ! Images Formed By Concave Mirror But if we increase the distance between the object and the mirror, we will obtain an image which is real and inverted. The nature of it depends on the position of the object, if it is placed very close to the mirror, the image would be virtual and erect. Light falling on such a mirror converges at a point and reflects back from the surface of the concave mirror, therefore such mirrors are also called converging mirrors.Īn image formed by the concave lens can be real and inverted as well as virtual and erect. Portions cut out from a hollow spherical mirror with their inner surface as reflecting surface, such mirrors are called Concave Mirror. Applications of Concave Mirror and Lens.
