“Concave” vs. “Convex”: What’s The Difference? - Dictionary

WebA Galilean telescope is defined as having one convex lens and one concave lens. The concave lens serves as the ocular lens, or the eyepiece, while the convex lens serves as the objective. The lens are situated on either side of a tube such that the focal point of the ocular lens is the same as the focal point for the objective lens. WebA convex lens is a converging lens that works much like a concave mirror. This kind of lens is thicker in the middle and thinner towards the edges. A convex lens makes the object appear magnified when viewed through it. You might have seen the magnifying glasses used to read the very small print. in wall air conditioner covers
