When the concave mirror is placed very close to the object, a virtual and magnified image is obtained, and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.
When an object is placed in front of a concave mirror, a magnified image is formed when the object is close to the mirror, and an inverted image is formed when the object is farther away. On the other hand, a convex mirror always forms a small and upright image of the object.
Feb 20, 2022 · The characteristics of an image formed by a flat mirror are: (a) The image and object are the same distance from the mirror, (b) The image is a virtual image, and (c) The image is situated behind the mirror.
If the object placed between the focal point and vertex then virtual image is formed behind the mirror. Since the rays reflected from the mirror do not intersect, their extensions behind the mirror intersect and virtual image is formed. Image is magnified in size and erect unlike the real images.
Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.
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.
Jan 26, 2023 · The figure below shows a real image formed by a concave spherical mirror. For the purpose of clarity only two principle rays are shown in the figure. The height of the object is labeled as \(h_o\), while the height of the image is marked \(h_i\).
Mar 12, 2024 · We will use the law of reflection to understand how mirrors form images, and we will find that mirror images are analogous to those formed by lenses. Figure \(\PageIndex{1}\) helps illustrate how a flat mirror forms an image.
The goal of a ray diagram is to determine the location, size, orientation, and type of image that is formed by the concave mirror. Typically, this requires determining where the image of the upper and lower extreme of the object is located and then tracing the entire image.
Number of images formed in two parallel mirror are infinite because an image formed by one mirror can act as an object for the second mirror. And every image formed by the second mirror can act as an object for the first mirror.
