- Definition: An object or a function is concave if it curves inward. In simple terms, it’s hollow or bowed in, much like a cave.

Feb 27, 2024 · In a concave lens, parallel rays of light are made to diverge (spread out) from a point. This lens is sometimes referred to as a diverging lens. The principal focus is now the point from which the rays appear to diverge from. Parallel rays from a concave lens appear to come from the principal focus. Representing Lenses.
convex lens: A lens having at least one convex surface, such that light passing through it, may be brought to a focus. concave lens: A lens having at least one concave surface, such that light rays passing through it bend away from its optical axis.

Sep 9, 2023 · Concave lenses focus light inside the curve of the lens, while convex lenses focus light using the outer curve. A lens that curves like a “C” (no flat side) is both concave or convex, depending on which side of the lens you view from.
The ray nature of light is used to explain how light refracts at planar and curved surfaces; Snell's law and refraction principles are used to explain a variety of real-world phenomena; refraction principles are combined with ray diagrams to explain why lenses produce images of objects.
An object placed at a finite distance from the lens forms a virtual image between the pole and the focus of the convex lens. As a result, the size of the image is smaller than that of the object.
