A real image is an image that can be projected onto a screen. Concave mirrors can form inverted and real images and also virtual and erect images. The focal length of a concave mirror is negative. What types of images are formed by convex and concave mirrors? image formed by the concave lens will be erect , virtual and smaller than the size of object. When object lies at 2F, 4. Lenses 1. A lens with one convex and one concave side is convex-concave or meniscus. The image formed is virtual as we see that the light appears to pass through the focus behind the lens. When object lies at infinity, 2. When you keep an object in front of a concave mirror, an enlarged image of the object is formed when it is kept close to the mirror and an inverted image of the object is formed when it is kept at a distance. On the contrary, the image For a magnified image to be observed the distance between the object and the lens has to be shorter than the focal length of the lens. Answer: Concave lens; Convex lens. Generally, a convex lens forms a real image, but it can also create a virtual image when the object is in the center of the focus and the optical center. Concave lenses are to treat nearsightedness or myopia. The virtual image Real images are formed when rays actually pass one to form an image. This kind of image cannot be projected on a screen usually upright. 1. A concave mirror and a Converging lens will only Biconcave Lens: The surface having a concave lens on both sides is termed as a biconcave lens. A convex lens varies a lot from the convex mirror.

No, convex lens can form both real and virtual images depending upon the position of object placed in front of lens. F. F'. What is real and virtual image? A concave lens Characteristics of Images Formed by a Convex Lens. Thus, the image does not exist in reality but the image appears to be formed at the point A concave mirror and a converging lens will only produce a real image if the object is located beyond the focal point (i.e., more than one focal length away). What is the main formula that relates the object and image distances in spherical mirrors/lenses? The object in this case is beyond the focal point, and, as usual, the place where the refracted rays appear to diverge from is the location of the image. To confirm the lens equations. The image of an object is found to be upright and reduced in size. The image which cannot be obtained on a screen is called a virtual image. A magnifying glass is a convex lens which produces a magnified image of an object. A concave mirror and a Converging lens will only produce a real image if the object is located beyond the focal point (i.e., more than one focal length away). Therefore, the image formed will be an inverted image. A convex mirror always forms a small and an erected image of the object. A ray diagram is a tool used to determine the location, size, orientation, and type of image formed by a lens. Concave lenses represent the type of lenses which are slender at the centre than at the borders. In these diagrams, F is the focal length of the lens, and 2F is twice the focal length of the lens.
