The term "concave-convex lens" is a compound noun.
/kɒnˈkeɪv.kənˈvɛks lɛnz/
A concave-convex lens is a type of lens that has one surface that is concave (curved inward) and another that is convex (curved outward). This design allows the lens to focus light in specific ways, which can be important in a variety of optical applications such as cameras, microscopes, and glasses.
Frequency of Use: This term is primarily used in technical contexts, particularly in physics and optics. It is more frequently encountered in written texts, such as textbooks, research articles, and manuals, rather than in everyday oral speech.
Example Sentences:
1. The optician recommended a concave-convex lens for my new glasses to correct my vision.
Оптометрист порекомендовал мне линзу выпукло-вогнутую для новых очков, чтобы исправить зрение.
In physics class, we learned that a concave-convex lens can produce both real and virtual images.
На уроке физики мы узнали, что выпукло-вогнутая линза может создавать как реальные, так и виртуальные изображения.
The camera used a concave-convex lens to achieve a clearer focus on the subject.
Камера использовала выпукло-вогнутую линзу для достижения более четкого фокуса на объекте.

The term "concave" comes from the Latin word "concavus," meaning "hollow" or "arched," while "convex" derives from the Latin word "convexus," meaning "arced" or "vaulted." The combination of both terms is used in optics to describe the specific shape and function of the lens.
