uses of concave and convex lens
Answers
convex lenses can be used to get magnified or larger images of objects.as it shows small images,it can be used as spectacles for short sightedness (myophia).it can also be used in flashlights, peepholes, binoculars, telescopes, and in photography.it is also kept in curves of road to get a better view of the coming vehicles which cannot be seen by the other driver.it can reduce accidents.
concave lens can be used as reflecting surfaces in headlights of cars, in telescopes, in satellite dishes, as shaving mirrors, in torch and etc.
》A concave lens -- also called a diverging or negative lens -- has at least one surface that curves inward relative to the plane of the surface, much in the same way as a spoon. The middle of a concave lens is thinner than the edges, and when light falls on one, the rays bend outward and diverge away from each other. The image you see is upright but smaller than the original object. Concave lenses are used in a variety of technical and scientific products.
Examples:- Binoculars, Flashlight, Cameras, Peephole, Lasers, etc
》Uses of convex lens are in daily life are as follows : 1) Convex lens is used in microscopes and magnifying glasses to subject all the light to a specific point.
2) Convex lens is used as a camera lens in cameras as they focus light for a clean picture.
3) Convex lens is used in the correction of hypermetropia.
