The nature and size of the image formed by a convex lens and a concave mirror are determined by the object's distance from the lens or mirror.

A convex lens, also known as a converging lens, bends light rays towards a specific point known as the focal point. When an object is placed at a distance greater than the focal length of the lens, a real, inverted, and diminished image is formed. If the object is at the focal point, no image is formed. However, when the object is between the lens and the focal point, a virtual, upright, and magnified image is formed.

On the other hand, a concave mirror, or a diverging mirror, reflects light rays away from a single point, also known as the focal point. When an object is placed at a distance greater than the focal length of the mirror, a real, inverted, and diminished image is formed. If the object is at the focal point, again, no image is formed. However, when the object is between the mirror and the focal point, a virtual, upright, and magnified image is formed.

The size of the image formed by both the convex lens and the concave mirror can be calculated using the lens/mirror equation: 1/f = 1/v + 1/u, where f is the focal length, v is the image distance, and u is the object distance. The magnification of the image can be calculated using the magnification equation: m = -v/u. If the magnification is greater than 1, the image is magnified. If it is less than 1, the image is diminished. If it is negative, the image is inverted.

In conclusion, the nature and size of the image formed by a convex lens and a concave mirror depend on the object's distance from the lens or mirror. By understanding the properties of these optical devices and using the lens/mirror and magnification equations, one can predict the nature and size of the image formed.
