Answer:
Difference Between Convex and Concave Lens
convex lens vs concave lensThe lens is understood as a curved and transparent piece of glass or plastic, which focuses and refracts light rays in a certain manner. The curvature of the object ascertains the extent to which light is bent and in which direction. They are used in spectacles, microscope and telescopes. Based on the shape, the lens can be grouped as a convex lens or concave lens. The former brings together the parallel beam of light, while the latter disperses it.
So, the point of focus in case of the convex lens is the point where all the light rays meet, i.e. point of convergence, but if we talk about the concave lens, the focal point is the point from where the light rays seem to diverge, i.e. point of divergence.
Let’s understand the difference between convex and concave lens, with the help of the diagram below.

BASIS FOR COMPARISON CONVEX LENS CONCAVE LENS
Meaning Convex lens refers to the lens which merges the light rays at a particular point, that travels through it. Concave lens can be identified as the lens which disperses the light rays around, that hits the lenses.
