Note that the real image is inverted. The image happens to be larger than the object. That happens because the object is between f and 2f away from the lens; if the lens were farther away than 2f, the image would be closer to the lens than 2f, and would be smaller than the object. The position of the image can be found through the equation:.
Here, the distances are those of the object and image respectively as measured from the lens. However, image distances are usually measured as the smallest distance measured perpendicularly to the mirror. For middle images, this distance would be measured to an extended mirror line and it would be the same distance as that from the object to that same mirror. C is false; the middle image, unlike the primary images, does not exhibit this feature of left-right reversal.
D is false; the middle image is a virtual image; it is upright and located behind the mirror like any virtual image. E is true; just look at the middle image and you will see an upright image. F is false; a magnification of -1 means that the image would be inverted negative M and the same size as the object 1 ; the middle image is the same size as the object but it is not inverted.
G is true; light will reflect twice - once off each mirror - prior to traveling to the viewer's eye. Two plane mirrors are attached to form a dual mirror system with an adjustable angle. Consider two mirrors arranged at a 0-degree angle - parallel to each other. There would be an infinite number of images, one located directly behind the other forming a line which seems to extend forever.
Suppose the mirrors are adjusted to a degree angle see question 29 below. The mirrors would create 5 images of objects placed between the mirrors. Now suppose that the angle is increased to a degree angle see question 29 below. Finally, suppose the mirrors are adjusted to a degree angle to form a single plane. At such an angle, only one image would be formed.
As the angle is increased, the number of images decreases. C is true; a virtual image is reduced in size if formed by a convex mirror; it is magnified in size when created by concave mirrors; it is the same size as the object when created by plane mirrors. D is true; convex and plane mirrors always form virtual images; concave mirrors will form virtual images of objects placed between the focal point and the mirror.

What image is formed in a plane mirror or a cinema screen? What type of image is formed on a plane mirror? All you have to do is stare at a selfie camera, flip and capture your photo. One major factor is that photos generally show us the reverse of what we see in the mirror.
When you take a photo of yourself using some but not all apps or the front-facing camera on an iPhone, the resulting image captures your face as others see it. Instead, if you hold your phone away from you and zoom in, you will look completely different. A mirror image is called a mirror image because it reverses things from left to right.
You usually see a mirror image of yourself. In contrast, if you look at a normal camera photo, you see yourself as another person would see you.
