Which Greek letter is represented by the answer "Λ"?

The Greek letter "Λ" is indeed represented as Lambda, which is the correct choice. Lambda is the 11th letter of the Greek alphabet and is commonly used in various contexts, such as mathematics, physics, and engineering, often to represent variables or specific constants. In the case of Greek life, Lambda is an important symbol within the fraternity and sorority community.

Each of the other Greek letters mentioned—Kappa, Psi, and Omega—corresponds to different symbols that are distinct from "Λ." Understanding the Greek alphabet and the significance of each letter is crucial in many areas, including the study of fraternities and sororities, where these letters are often employed in names and to represent chapters.
