Apr 16, 2024 · Class 10. Chapter 10 Class 10 - Light - Reflection and Refraction. Concepts. Uses of Concave and Convex Lens. Last updated at April 16, 2024 by Teachoo. We saw that, image formed by convex lens is. Now, let us see where convex lens is used. Convex lens is used as. It is used as Magnifying Glass. It is used to Make Microscope.
A lens is a transmissive optical device that disperses or focuses a light ray by means of refraction. Concave means hollowed inward or curving in; so, concave lenses are hollowed inward. A concave lens is also called as a negative lens or a diverging lens.
Concave Lenses. When an object is placed at infinity, a virtual image is formed at the focus. The size of the image is highly diminished and point size. When an object is placed at a finite distance from the lens, a virtual image is formed between the optical centre and the focus of the convex lens.
6 days ago · A convex lens is being used for the correction of the long sight problem whereas a concave lens is being used for the correction of the short sight problem. Convex lenses always have a positive focal length whereas concave lenses have a negative focal length.
Solution. Uses of the convex lens: It is used in building microscopes. Used as a magnifying glass. used to adjust vision on spectacles. They are extensively employed in cameras to focus on and magnify an image. Uses of the concave lens: Peepholes use a concave lens. They are used to adjust vision on spectacles.

Uses of Convex Lens. A convex lens is a lens that converges ray of light that is traveling parallel to its principal axis. A convex lens is relatively thick at the middle and thin at the upper and lower edges. The edges of the rays curved outward rather than inward.
Prepare for class 10 CBSE exam for the chapter Light, by recalling the concepts of concave/convex mirrors and lenses.
3 days ago · A concave lens is a diverging lens that helps people view objects at large distances if they are dealing with Myopia; however, for people dealing with hypermetropia, a converging lens, convex lens is used, which we will discuss in this article.
Concave lenses, with their inward curve, create divergent light rays. When a ray parallel to the principal axis hits the lens, it refracts outward as if coming from the focal point. Another ray, passing through the lens center, doesn't refract.
