[196][197]
The above statement[198][199] is True.
A biconvex lens is a type of basic lens that has two convex surfaces with the same radius of curvature and is shaped like a sphere. This kind of lens is also known as a convex-convex lens. The bi-convex (Double-Convex) lenses have the same radius of the curvature upon both sides of the lens and feat similarly to plano-convex lenses by focusing parallel rays of affable a single reduction. As a guideline, the bi-convex lenses battle previously minimum anomalies at conjugate ratios surrounded by [200][201]5:1 and [202][203][204][205]1:5.
