characteristics of image formed by convex mirror

Object is positioned at Infinity We use them because we know the paths of them. The table shows what happens to the image as an object is brought from infinity toward a convex lens. 1), and spherical mirrors (concave and convex) as shown in Fig. When parallel rays (could be from a distant object) incident on a concave mirror, the reflected rays converge to a focal point (F), hence also called converging mirror. a. On the contrary, concave mirrors are used in torches and vehicle headlights. In this section, let us look at the types of images formed by a convex mirror. The characteristics of images formed by Plane mirrors are interesting! Characteristics of the Image Formed by a Concave Mirror According to the Position of the Object When the object is at infinity in the case of a concave mirror, the image formed has the following properties. The three types of images formed by mirrors (cases 1, 2, and 3) are exactly analogous to those formed by lenses, as summarized in the table at the end of "Image Formation by Lenses." Therefore, the properties of the images formed here are formed behind the mirror, images are highly enlarged, images are virtual and erect. Object Position Image Position Image Characteristics; At infinity: At focal point: Image is a point: Moving toward 2F: Moving from F toward 2F: … Ray Diagrams for a Convex Mirror. Such an image is called a virtual image. 2. When an object is located at infinity, a virtual image is created at the focus point. 1. Image Formation in Concave Mirrors While drawing images of the object we benefits from the special rays given above. Uses of the concave mirror and the convex mirror in our daily life. Convex mirrors are used as rear-view mirrors in cars, to enable the driver to see the traffic behind him. 1. The image formed by a convex mirror is a virtual image, while concave mirror forms a real or virtual image, depending on the position of the object. The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. The concave lens is known as the diverging lens because it diverges the rays after they pass through it, The image formed by the concave lens is a virtual image because it can not be received on a screen. Comparison Video Let’s start drawing images of the objects located in different parts of the mirror. In case, of a convex mirror, there are only two possible positions where the object can be positioned and an image can be formed. The three types of images formed by mirrors (cases 1, 2, and 3) are exactly analogous to those formed by lenses, as summarized in the table at the end of Image Formation by Lenses. It is easiest to concentrate on only three types of images—then remember that concave mirrors act like convex lenses, whereas convex mirrors act like concave lenses. 2. A diminished image formed by a convex mirror while a concave mirror formed a magnified image. Convex mirrors are used as side mirrors of automobiles while concave mirrors are used in torch lights etc. If the object placed at the center of the mirror, image is also formed at center, real, inverted and with the same size as object. Unlike images formed by concave mirrors, an image formed by a convex mirror cannot be projected on a screen. But the characteristics of images formed by Spherical Mirrors are more fun! The properties of the image formed by a plane mirror image formation by plane mirrors (Fig. The image formed by a convex mirror cannot be projected on a screen while image by a concave mirror can be projected on a screen. The image is real. Image Characteristics for a Convex Lens.
