A converging lens will produce a collimated beam of light (parallel rays) with the lamp at the focal point. This happens because the lens refracts the light rays in a way that they become parallel as they exit the lens.
A converging mirror will not produce a real image if the object is placed between the focal point and the mirror. In this case, the mirror will produce a virtual image on the same side as the object.
An inverted and smaller real image is produced by a converging lens when an object is placed twice as far as the focal point. The image is located between the focal point and twice the focal length from the lens.
if the focal length is greater than the object distance from the lens
The object must be located beyond the focal point of the mirror for a converging mirror to produce a real image.
You must stand closer to the converging mirror than its focal point. This position will allow the converging mirror to produce an inverted image of yourself.

A converging mirror will not produce a real image if the object is placed between the focal point and the mirror. In this case, the mirror will produce a virtual image on the same side as the object.
A real object placed beyond the focal length of a converging lens will produce a real image. This occurs when the object distance is greater than the focal length of the lens.

A converging lens, such as a convex lens, has a focal point where parallel rays of light converge after passing through the lens. This focal point is where the image of an object placed at infinity will be formed.
When the object lies within its focal length then no real image can be produced
When an object is placed beyond the focal point of a converging lens, a real and inverted image is formed on the opposite side of the lens. If the object blinks, the image will momentarily disappear and reappear, but the characteristics of the image formation will remain the same.
A converging lens forms a real image when the object is placed beyond the focal point, and the light rays converge to a point on the opposite side of the lens. A virtual image is formed when the object is placed between the lens and the focal point, and the light rays appear to diverge from a point behind the lens.
