The size of the image is a scaled representation of the original object, typically smaller or larger. The relationship between the size of the image and the size of the original object is determined by the magnification factor of the optical system used to capture the image.
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 change in size of an image compared with the size of an object is termed magnification. This can be calculated as the ratio of the size of the image to the size of the object. Magnification can be expressed as magnification = image size / object size.
The height and width of the object are the physical measurements of the object itself, while the height and width of the image are the representation of those measurements in a picture or visualization. The size of the object in the image can be adjusted to fit the dimensions of the image through scaling or cropping.
A reflected image in a plane mirror is laterally inverted, meaning it appears reversed from left to right compared to the original object. The image is the same distance behind the mirror as the object is in front of it, and the size of the image is equal to the size of the object.
To find the magnification of a lens, you can use the formula: Magnification image height / object height. This formula compares the size of the image produced by the lens to the size of the original object. The magnification value will tell you how much larger or smaller the image appears compared to the object.

With a scale factor of 1, the image is exactly the same size as the original object.
One way to measure the size of an object from an image is to use a known reference object of a standard size in the same image. By comparing the size of the reference object to the size of the object you want to measure, you can calculate the size of the object in the image.

A scale factor of one means that there is no change in size.
To find the magnification of a lens, you can use the formula: Magnification image height / object height. This formula compares the size of the image produced by the lens to the size of the original object. The magnification value will tell you how much larger or smaller the image appears compared to the object.
Your magnification factor is SID divided by OID. [MF = SID/OID] So for example: If your SID was 40 and your SOD was 32 Your magnification factor = 40/32 = 1.25 -- This means the image will appear 25% larger than the actual object. (It's the size of 1 plus 25 percent more of the original.) Example 2 if you're trying to figure out original object size: Your object size equals your image size divided by the magnification factor (MF). [object size = image size/ MF] If you have an object on an image that measure 70 inches when your SID was 100 and your OID was 65, how big was the original object? MF=100/65= 1.54 (rounded) Object size = 65/1.54 = 42.21 The object imaged was 42.21 inches before magnification.
In a plane mirror, the image size is of same size as that of the object, but in the rear view mirror, the image size is smaller than that of the mirror.
A magnification of 40 times is needed to achieve a 120mm image of a 3mm object. This is calculated by dividing the desired image size (120mm) by the original object size (3mm). So, a magnification factor of 40x would enlarge the 3mm object to 120mm.
A regular reflection forms an image that is identical in size and shape to the original object, but appears to be reversed left to right.
