DOUBLE CONVEX Meaning and
Definition
-
A double convex lens refers to a type of lens that possesses a curved surface on both sides, wherein each surface is rounded outwards. This lens shape results in a greater thickness at the center compared to the edges, creating a convex appearance on both sides. The center of the lens is typically the thickest point, while the edges are comparatively thinner.
Double convex lenses are commonly used in optics and are known for their ability to focus light. Due to their shape, they have a positive focal length, meaning they converge light rays that pass through them. These lenses are convex on both sides, enabling them to bend light inward, bringing it to a focal point on the opposite side.
The significance of using double convex lenses lies in their role in various optical applications. They are often utilized in microscopes, telescopes, and camera lenses, contributing to image magnification and the correction of optical aberrations. The symmetrical design of double convex lenses allows for the reduction of certain optical distortions, ensuring clearer and more accurate imaging.
In summary, a double convex lens is a type of lens with two outwardly curved surfaces, resulting in a thicker center and thinner edges. It possesses a positive focal length and is widely used in optics for its ability to focus light and correct optical aberrations in various optical instruments.

Etymology of DOUBLE CONVEX
The word "double convex" is derived from a combination of two words:
1. "Double" comes from the Latin word "duplus", which means "twofold" or "double". It entered the English language through Old French and Middle English.
2. "Convex" comes from the Latin word "convexus", which means "curved" or "rounded". It is derived from the prefix "con-" (with or together) and the word "vertex" (meaning "turn" or "bend").
When combined, "double convex" refers to a lens or mirror that is curved outward on both sides, creating a bulging or rounded shape.
