An image in a plane mirror is created by the light rays reflecting off the reflective surface of a mirror. The image is always virtual because the light rays remain parallel, meaning they never pass through a focal point. The image is actual size, inverted, and always virtual. When light strikes a plane mirror, the angle of incidence will always equal the angle of reflection.
An inverted and real image is formed by an object placed beyond the center of curvature on the principal axis of a concave mirror. The size of the image will be smaller than the object.
A concave mirror that has a focal length smaller than its radius of curvature will produce only virtual images. This is because the image is formed on the same side of the mirror as the object, resulting in a virtual image that cannot be projected onto a screen.
An upright image, which is called a virtual image. If the focal point was outside of a concave mirror, then it would be a real image, which is inverted.
Concave mirrors can form both real and virtual images. Real images are formed when the reflected light rays actually converge at a point in front of the mirror, whereas virtual images are formed when the light rays appear to diverge from a point behind the mirror. The type of image formed depends on the position of the object relative to the focal point of the mirror.
A typical mirror in a person's house is an example of a flat or plane mirror. These mirrors produce virtual images that appear upright and the same size as the object being reflected.
A virtual erect image of the same size of the object is formed.
Plane and convex mirrors produce only virtual images.
An inverted and real image is formed by an object placed beyond the center of curvature on the principal axis of a concave mirror. The size of the image will be smaller than the object.

Concave mirrors can form both real and virtual images. Real images are formed when the reflected light rays actually converge at a point in front of the mirror, whereas virtual images are formed when the light rays appear to diverge from a point behind the mirror. The type of image formed depends on the position of the object relative to the focal point of the mirror.
A concave mirror is better for gathering light on a telescope because it can focus incoming light rays to a single point, known as the focal point. This allows for a sharper image to be formed compared to a plane mirror, which simply reflects light without focusing it. The shape of the concave mirror also helps to increase the amount of light collected, making it more effective for astronomical observations.
image formed by the concave lens will be erect , virtual and smaller than the size of object.
The name of this type of instrument is derived from the fact that the primary mirror reflects the light back to a focus instead of refracting it. The primary mirror usually has a concave spherical or parabolic shape, and, as it reflects the light, it inverts the image at the focal plane.
