The image distance is the distance from the lens to where the image is formed, while the object distance is the distance from the lens to the object. In general, for real images, the image distance is different from the object distance. For virtual images, the image distance is negative and the object distance is positive.
Moving the object away from the lens increases the object-image distance. According to the thin lens equation, as the object-image distance increases, the image distance increases incrementally more than the object distance. This results in a smaller image size due to the inverse relationship between image size and image distance.
The size of the image is based on the distance between the object and the lens, as well as the focal length of the lens. The image can be the same size as the object if the object is at the focal point and the lens follows the 1/f = 1/do + 1/di equation.
The distance from the object to the mirror is equal to the distance from the image to the mirror in a plane mirror. The image appears to be as far behind the mirror as the object is in front of it, so the apparent distance from the image to the mirror is equal to the actual distance from the object to the mirror.
The focal length of a lens is related to the object distance and image distance by the lens equation: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. This equation describes how the lens focuses light rays from an object at a certain distance to form an image at a specific distance.
As the object distance increases, the image distance also increases. This relationship is governed by the lens or mirror equation, which shows that when the object is moved farther from the lens or mirror, the image is also formed farther from the lens or mirror.
The distance of the object from the mirror line should equal the distance of the image from the mirror line.
Moving the object away from the lens increases the object-image distance. According to the thin lens equation, as the object-image distance increases, the image distance increases incrementally more than the object distance. This results in a smaller image size due to the inverse relationship between image size and image distance.
For a flat mirror, the object distance is equal to the image distance. This means that the image formed by a flat mirror is the same distance behind the mirror as the object is in front of it.
The size of the image is based on the distance between the object and the lens, as well as the focal length of the lens. The image can be the same size as the object if the object is at the focal point and the lens follows the 1/f = 1/do + 1/di equation.
The distance from the object to the mirror is equal to the distance from the image to the mirror in a plane mirror. The image appears to be as far behind the mirror as the object is in front of it, so the apparent distance from the image to the mirror is equal to the actual distance from the object to the mirror.
image distance is the distance from the point of incidence on the mirror, the where the image is reflected to.object distance is the distance from the actual object being reflected to the point of incidence on the mirror where it's reflected as an image.
The focal length of a lens is related to the object distance and image distance by the lens equation: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. This equation describes how the lens focuses light rays from an object at a certain distance to form an image at a specific distance.
As the object distance increases, the image distance also increases. This relationship is governed by the lens or mirror equation, which shows that when the object is moved farther from the lens or mirror, the image is also formed farther from the lens or mirror.
In a concave mirror, the relationship between object distance, image distance, and focal length is described by the mirror formula: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. As the object distance changes, the image distance and focal length will also change accordingly.
In a plane mirror, the image distance (di) is equal to the object distance (do). The image formed is virtual, upright, and the same size as the object, and it appears behind the mirror at the same distance as the object in front of the mirror.
The magnification equation for a concave mirror is given by the formula: M = - (image distance) / (object distance), where M is the magnification, image distance is the distance from the mirror to the image, and object distance is the distance from the mirror to the object. Negative magnification indicates an inverted image.
1.Image distance= object distance 2.Size of the image = size of the object 3.image is laterally inverted 4.Image is always virtual & erect
