when dealing with a flat mirror object-distance and image-distance should be equal.
The image seen in a plane mirror appears to be the same distance behind the mirror as the object is in front of it. This is because light rays reflect off the mirror and create a virtual image that appears behind the mirror at the same distance.
The image will be located the same distance behind the mirror as the object is in front of it, so the image will be 15 millimeters behind the mirror.
If our image is real and inverted and smaller than the object ,then it is a concave mirror; if the image is virtual and erect and larger than the object,then it is a convex mirror; if the image is of the same size as of the object,it is a plane mirror. that is how we can distinguish or identify which of the given mirrors are what. BUT if the angle is very small you cannot tell Plane is flat, convex it curves outwards and concave it curves inwards.
yes it always produces a virtual image. it is always erect. Its size is always diminshed. Distance from the mirror is always between Focus and Pole
In a plane mirror, the image appears to be the same size as the object, symmetrical to the object's position, and reversed from left to right. It is a virtual image, meaning it cannot be projected onto a screen.
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 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.
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.
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.
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
A plane mirror forms 1 virtual image and no real image. The virtual image is behind the mirror, at the same distance as the object in front of the mirror, erect, in mirror image left-right.
The distance between the image and the plane mirror is the same as the distance between the object and the mirror. Therefore, if the object is 15m away from the mirror, the image will also be 15m behind 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.
The distance between the object and mirror is 15 mm. The distance between the image and mirror is 15 mm. Therefore, the distance between the image and object is 15 mm plus 15 mm which equals 30 mm.
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
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.
