difference between concave and convex lens

All those devices which can focus a light beam are known as lenses, for e.g. The lens which merges the light rays at a particular point, that travels through it, are a convex lens. When a light ray falls on the surface of the lens then it bends the light rays passing parallel to its principal axis. However, in case the object is very near to the lens then the resultant image is virtual, erect, and magnified. It is called positive lens because of its positive focal length nature. The convex lens is curved towards the inside. However, in the convex lens, the edges are comparatively thinner than the center of the lens. In the concave lens, the path of the rays is traversed behind the lens so as to get the focal point.

The crucial difference between concave and convex lens is that a concave lens diverges the light rays that incident on its surface. An image cannot form on a screen in this case. Similarly, a concave lens is called diverging lenses because they cause parallel rays to diverge. Concave and Convex are two types of lenses that possess variation in physical shape as well as their properties. Pro Lite, Vedantu While the real and inverted image is formed from a convex lens. … Generally, forms real and inverted image. Lights, flashlights, laser, binocular etc. A convex lens is called as ‘converging lens’ or ‘positive lens’. So, when the light rays pass through it then despite bending towards a single point, it disperses. Convex Lens … It helps to magnify the things and make them look bigger. A type of optical lens whose surface is bulged in an outward direction making the center thicker than the edges. Thus, the above discussion between a concave and a convex lens concludes that both have different physical shapes and generates a different form of images when light rays incident on it thus have different applications. The key factor of differentiation between a concave and a convex lens is that a concave lens, Due to the nature of the lens, the incident light rays either converges or diverges after passing through it. The concave lens spreads out the light when it passes through the lens. In convex lens, the centre of the glass piece is thick whereas the edges are thin. The human eye, camera, telescope, microscope etc. Sorry!, This page is not available for now to bookmark. This lens is thick at the center as compared to the edge. Lens in human eye, microscope, telescope, etc. Difference between Concave and Convex Lens: Definitions Concave Lens Bound by two spherical surfaces this lens is thinner at the center and thicker at the edges. A concave lens is called as ‘Diverging lens’ or ‘Negative lens. Difference between Concave and Convex lens A lens is an optical device that converges or diverges a ray of light by means of refraction. As the parallel rays converge, the convex lens is termed as a converging lens. It is used to correct short-sightedness or myopia. The power of the lens is defined in terms of a measure of convergence or divergence, the lens introduces to the light rays that incident on it. A concave lens exhibits a cave-like structure from the outside as it has a thinner middle portion and thick edges. Thus, the concave lens is also known as a. Also, the direction of bending depends on the curvature and material. When light passes through the lens, it bends the light rays towards each other. Thus, concave lenses are diverging in nature.
