Different types of images can be formed by a concave mirror by changing the position of the object from the concave mirror. Therefore different types of images are formed when the object is placed 1. At the infinity 2. Beyond the centre of curvature 3. At the...

The position of the image formed by spherical mirrors can be found by taking two rays of light coming from a point on the object which intersect each other to form an image. Following are the rules which are used for obtaining images formed by spherical mirrors....

Image An image may be defined as that point, where the light rays coming from an object meet or appears to meet after reflection or refraction. In this definition the word ‘object’ may be defined as anything which gives out light rays. The objects can be of two types:...
