There are four mirrors labelled as I, II, III, and IV. Mirrors I and IV can form virtual and small images only. Mirror III can form an image that can be obtained on a screen. Mirror II cannot form real images of objects. Which of the given mirrors can form an inverted image of the object?

Hint: A mirror is a reflective surface that is smooth and highly polished. Plane mirrors are the most widely used mirrors. A part of a spherical reflection surface is a spherical mirror. Convex and concave mirrors are the two types of spherical mirrors.

Complete answer:
Convex Mirror: A convex mirror is a curved mirror with a reflecting surface that bulges outwards towards the light source. Since convex mirrors reflect light outwards, they cannot be used to concentrate light. The image is virtual, upright, and smaller than the object, but as the object approaches the mirror, it grows larger. Diverging mirrors are another name for these types of mirrors.

Concave Mirror: The reflective surface of a concave mirror caves inwards. Light is converged by concave mirrors to a single focal point. As a result, they're also known as converging mirrors. They're used to concentrate light. The size of the image created by a concave mirror varies depending on the object's location in relation to the mirror. Depending on the orientation of the object, the image may be actual or simulated, upright or reversed, magnified, reduced, or the same size as the object.

On a frame, the image created by mirror III can be seen. As a result, mirror III will produce a true image. This indicates that mirror III is concave. Mirror III can produce inverted images since only concave mirrors can produce true and inverted images of objects.

Note:The image formed by the concave mirror is determined by two parameters: the object distance and the focal length of the mirror. A magnified and erect virtual is created when an object is positioned between the pole and the focus of a concave mirror.
