As an expert in the field of optics, I can provide a detailed explanation of image formation in mirrors, specifically addressing the question of whether convex mirrors produce real images.
Mirrors and Image Formation:
Mirrors are optical elements that reflect light and are commonly used to form images. There are two primary types of mirrors: convex and concave. Each type has distinct properties when it comes to image formation.
Convex Mirrors:
A convex mirror has a reflective surface that bulges outward, away from the viewer. It is widely used in various applications, such as car side mirrors, to provide a wider field of view.
Virtual Images:
When discussing the nature of images formed by mirrors, it's important to understand the difference between real and virtual images. A real image is formed where actual light rays converge to create an image that can be projected onto a screen. A virtual image, on the other hand, is formed where the extensions of the reflected light rays appear to converge. Virtual images cannot be projected onto a screen because the light does not actually pass through the point of convergence.
Convex Mirrors and Real Images:
Now, to directly address the question: convex mirrors do not produce real images. The statement "Plane mirrors and convex mirrors only produce virtual images" is partially correct; plane mirrors always produce virtual images, but the assertion that convex mirrors only produce virtual images is not entirely accurate. It depends on the position of the object relative to the mirror.
Focal Length and Image Formation:
The ability to form a real image with a mirror is tied to its curvature and the object's distance from the mirror. For a convex mirror, the focal length is virtual and is located behind the mirror at a distance equal to the mirror's radius of curvature. If an object is placed at a distance greater than the mirror's radius of curvature (which is effectively the same as saying it's at a distance greater than the focal length, given that the focal length is virtual), the mirror will indeed produce a virtual image. However, if an object is placed at a distance less than the mirror's radius of curvature, the light rays will diverge after reflection, and no image (real or virtual) will be formed on the other side of the mirror.
Upright and Reduced Images:
The statement "The image of an object is found to be upright and reduced in size" is a general characteristic of images formed by convex mirrors. Because the reflective surface of a convex mirror is curved outward, the light rays diverge after reflection. This divergence causes the image to appear smaller than the object, and since the light rays are diverging, the image is virtual and upright.
Summary:
In summary, convex mirrors typically produce virtual images that are upright and reduced in size. However, it is not correct to say that they are only capable of producing virtual images without considering the object's position relative to the mirror. If an object is within the mirror's radius of curvature, no image is formed. Understanding the principles of optics and the properties of mirrors is crucial for accurately describing and predicting the behavior of light and the formation of images.

Plane mirrors and convex mirrors only produce virtual images. Only a concave mirror is capable of producing a real image and this only occurs if the object is located a distance greater than a focal length from the mirror's surface. 10. The image of an object is found to be upright and reduced in size.
