The distance of the object from the mirror line should equal the distance of the image from the mirror line.
1/object distance + 1/ image distance = 1/focal length
The answer is 15 millimeters behind the mirror, and the distance from the actual object to the image is 30 millimeters. Plane mirrors have a flat focus that places the image as far behind the mirror as you are in front of it.
All images in plane mirrors are virtual, meaning they cannot be projected onto a screen as they appear to be located behind the mirror. These images are also laterally inverted, which means that they are reversed from left to right. Additionally, the size of the image is equal to that of the object, and the distance of the image from the mirror is the same as the distance of the object from the mirror.
Usually as we say the details of the image we point out their, size, position, type and nature. In case of plane mirror, size = same size of the object position = at the same distance as the object is in front of the mirror type - erect one nature - virtual image. This means could be seen but not be caught on a screen.
same distance
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.
when dealing with a flat mirror object-distance and image-distance should be equal.
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.
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.
Characteristics of an image formed by the plane mirror are :- * Virtual and erect (up right ) . * The image is of same size as that of the object . *The image is far behind the mirror as the object is in front of it . *The image is laterally inverted .
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.
It's a virtual reflection of the object which appears as an image as much behind the mirror as the distance of the object in front.
