# Uses of Convex Lenses :, Convex lenses are used as a magnifying glass., , In the manufacturing of spectacles, camera,, microscope, telescope and binoculars, convex lenses, are used., , # Concave Lens (Diverging Lens), , A concave lens is a lens which is thinner in the, middle than at the edge. A parallel beam of light falls, on a concave lens as shown in the figure. After, passing through the concave lens, the rays of light, are diverging (or spreading out)., , Since a concave lens diverges light rays falling on it,, therefore, it is also called a diverging lens., , Image Formed by a Concave Lens :-, In the case of a convex lens, we have studied that, the nature of image formed depends on the distance, of the object from the convex lens. But, this is not, followed in the case of a concave lens., , Let us perform an activity to understand the, formation of an image by a concave lens., , # Uses of Concave Lenses :-, In order to see the image of the person standing, outside, concave lenses are used in the peepholes in, the door of hotel rooms., , Concave lenses are used in making spectacles.
