true/false A lens that converges light is concave
Not true. You are going to have to do some work here, I already know the material.
True. A lens that converges light is concave.
To understand why, let's first define what a lens is. A lens is a transparent object with curved surfaces that refracts (bends) light as it passes through. There are two main types of lenses: convex and concave.
In the case of a concave lens, its shape is thinner in the center and thicker at the edges. When light rays pass through a concave lens, they diverge or spread out. This means that the parallel rays of light coming towards the lens will be refracted in such a way that they move further apart.
On the other hand, a convex lens has a shape that bulges outwards in the center and is thicker in the middle. When light passes through a convex lens, it converges or comes together. This means that parallel rays of light coming towards the lens will be refracted in such a way that they come closer together at a focal point.
Therefore, since a lens that converges light is causing the rays to come together, it must be a convex lens. Hence, the statement that a lens that converges light is concave is false.
