If the Object you are 'focused' on stays in the same relative position to the lens, then the image will appear SMALLER on the Focal Plane.
For example, the image using a 50mm lens will be LARGER than using a 28mm lens.
The focal length of a single concave mirror affects the formation of an image by determining the distance at which the image is formed. A shorter focal length results in the image being formed closer to the mirror, while a longer focal length results in the image being formed farther away.
The limit of the object distance to produce a real image is twice the focal length of the lens or mirror. This occurs when the object distance is equal to the focal length, resulting in the image distance being at infinity. At distances greater than twice the focal length, the real image becomes smaller and inverted.
To calculate magnification from the focal length of a lens, you can use the formula: Magnification (Image distance / Object distance) (focal length / focal length - object distance).
When an object is placed closer to a concave mirror than its focal length, the image formed is virtual, upright, and magnified. The image is located behind the mirror, and the rays of light appear to diverge from a point behind the mirror rather than converging at a real focal point.
In a concave mirror, the relationship between object distance, image distance, and focal length is described by the mirror formula: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. As the object distance changes, the image distance and focal length will also change accordingly.
The magnification of the telescope image is(focal length of the objective) divided by (focal length of the eyepiece).The focal length of the objective is fixed.Decreasing the focal length of the eyepiece increases the magnification of the image.(But it also makes the image dimmer.)

1/object distance + 1/ image distance = 1/focal length
In a concave mirror, the relationship between object distance, image distance, and focal length is described by the mirror formula: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance.

The focal length of a convex lens determines the magnification of the image produced by the magnifying glass. A shorter focal length will result in a larger magnification, making the image appear bigger. Conversely, a longer focal length will result in a smaller magnification, making the image appear smaller.
The focal length of the main optical system and the focal length of the lens forming the image.
A convex lens converges light rays to a focal point, which creates a real and inverted image if the object is placed beyond the focal length. If the object is placed within the focal length, a virtual and upright image is formed.
The focal length of a concave mirror to form a real image is positive. It is equal to half the radius of curvature (R) of the mirror, and the image is formed between the focal point and the mirror.
