In the convex lens, the curve is outward facing, whereas, in the concave lens, the curve faces inward. When object place btwn Pole and Focus.. The disparity between concave and convex lenses will clearly be understood when contemplating the concave lens internally. Difference between Convex and Concave Lens Difference between Convex and Concave Lens. A convex lens focuses light rays, and therefore is also known as a converging lens. A lens can be defined as a transparent material (like a glass) that has either an open curved surface or one flat surface or two curved surfaces. Therefore concentric lenses are sometimes referred to as divergent lenses. Convex lenses are beneficial in treating presbyopia, or far-sightedness. Due to the law of refraction, light rays bend as they enter and leave the lens. A convex lens is a converging lens. Keywords Related to the Lens. Used for the correction of problem in short sight. We will discuss here the difference between concave and convex lenses. Key Difference: Concave and convex are two basic types of lenses.A convex lens focuses light rays, whereas a concave lens causes the light rays to diverge. On the contrary, the image formed by the concave lens is erect, virtual and smaller, than the object. A convex lens is known as a converging lens, whereas a concave lens is also known as a diverging lens. Convex means “curved or rounded like the outside of a sphere or circle”. Concave and convex are also two types of spherical mirrors. A convex lens is thicker in the middle and thinner at the edges. (regardless of the object's position), Real , inverted, smaller than object, - object at F, Real , inverted, same size as object, - object at 2F, Real , inverted, larger than object, object between 2F and F, Virtual, upright, larger than object – behind object on the same side of the lens. These types of lenses are thicker in the middle than in comparison to their edges. Difference between Concave and Convex lens A lens is an optical device that converges or diverges a ray of light by means of refraction. The lesson provides a detailed insight into the difference between the concave lens and a convex lens in tabular form for easier understanding. Your email address will not be published. Comparison between Convex and Concave Lenses: A concave lens is thinner in the middle and thicker at the edges. All those devices which can focus a … Contents of the page. A convex lens is used to treat hyperopia or farsightedness. They produce real images, and therefore are mainly used in various optical instruments. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2020, Difference Between | Descriptive Analysis and Comparisons, thank u for giving this information it is used for understanding the chapter.now i can answer for any question, I don't get it that concave mirrors form real image while concave lenses form virtual ,is it true I don't get it?can somebody help me. The crucial difference between concave and convex lens is that a concave lens diverges the light rays that incident on its surface. Therefore, the image created by a concave lens is always a virtual image rather than a real image. Used for the correction of problem in long sight. The emerging rays do not actually intersect. Virtual, upright and smaller than the object between object and the lens. Yes its right but in a case concave mirror also form virtual and errect image. They are unable to form an image on a screen. Concave lens can be identified as the lens which disperses the light rays around, that hits the lenses. Conversely, the concave lenses are thinner at the centre and thicker at its edges, in structure. Key difference. Convex lenses round outward and cause light rays to converge. We will discuss here the difference between concave and convex lenses. These lenses can either be the concave and convex lens. They work on the principles of refraction, as they change the direction of light waves by refraction. Generally, a convex lens forms a real image, but it can also create a virtual image when the object is in the middle of the focus and optical centre. Conversely, the concave lenses are thinner at the centre and thicker at its edges, in structure.
