A concave mirror has a reflective surface that curves inward and away from the light source. Light is directed inward by concave mirrors to a single focal point. Contrary to convex mirrors, a concave mirror's image is dependent on the separation between the object and the mirror.
What are Lenses?
Lenses are spherical materials with one or more spherical surfaces. The two types of lenses bounded by two spherical surfaces are convex lenses (or converging lenses) and concave lenses (or diverging lenses).
Image Formation by Concave Lens: When the object is placed between the lens's optical center (O) and Infinity.
In this case,
The image formed by the concave lens will be between the first focus, F1, and the optical center O when the object is placed between infinity and the optical center O.
The image obtained will be virtual in nature and will be in erect form.
In addition, the size of the image formed will be reduced.
What happens when we look through a lens which is a concave lens?
A concave lens causes light rays to diverge in parallel and spread out so that they appear to come from a point behind the lens that is the focal point. The focal length of a lens is defined as the distance between the center of the lens and a focal point.
What type of image is formed by a Concave lens?
A concave lens produces a vertically inward, real or virtual, and always diminished image.
What is another name for Concave lenses?
The diverging lens is another name for a concave lens.
What is the image formed by concave lens?
A virtual image is always formed by a concave lens.
What is image formation in lens?
A virtual image is formed between the optical center and the focus of the convex lens when an object is placed at a finite distance from the lens. The image’s size is smaller than the object’s.
