diverging lens is concave or convex

A concave lens is a diverging lens..
Reason: Power of a concave lens is always less than the power of a convex lens, as power of concave lens is negative whereas power of convex lens is positive. They will behave as a diverging lens if focal length of convex lens is more. the lens which is thinner at the centre than at the edges is called a concave or diverging lens. Sometimes. Concave lenses are thinner at the middle. it diverges a beam of light on refraction through it or we can say a ray of light which is incident on the surface of the mirror, appears to converge after refraction. Assertion:A convex lens and a concave lens are kept in contact. hence, it has a virtual focus. Convex lenses are also known as converging lenses since the rays converge after falling on the convex lens while the concave lenses are known as diverging lenses as the rays diverge after falling on the concave lens. Rays of light that pass through the lens are spread out (they diverge). It is true that the primary lens used in binoculars and telescopes is a convex lens, but concave lenses are also involved. (ii) concave or diverging lens. A lens is a transparent material (either curved or flat surface) based on the principles of refraction. In this article, we will learn about image formation by concave and convex lenses. A convex lens or converging lens focuses the light rays to a specific point whereas a concave lens or diverging lens diverges the light rays. A concave mirror is a spherical mirror in which the reflecting surface and the center of curvature fall on the same side of the mirror. A concave lens is also referred to as a diverging lens, and these are curved so that the “bowl” of the lens is facing the object in question. Therefore, a transmissive optical device that focuses or … As mentioned above, the convention is that lenses like this are assigned a negative focal length, and the virtual image they produce is on the same side as the original object. Concave and convex are also two types of spherical mirrors. When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear to come from one point called the principal focus.. A lens which is double concave (concave on both sides) is definitely a diverging lens, because both sides act to diverge light that was originally parallel. Convex Lens If a piece of glass or other transparent material takes on the appropriate shape, it is possible that parallel incident rays would either converge to a point or appear to be diverging from a point. A convex lens is known as a converging lens, whereas a concave lens is also known as a diverging lens.
