What Are Greek Letters?

Greek letters are characters from the Greek alphabet, which has been used since the 8th century BCE. While originally used for writing the Greek language, these symbols now have widespread usage in mathematics, science, engineering, and other academic fields.

The Greek alphabet consists of 24 letters, each with an uppercase and lowercase form. These symbols are often used to represent specific concepts, constants, or variables in various disciplines.

For example, in mathematics, π (pi) represents the ratio of a circle's circumference to its diameter, while in physics, λ (lambda) represents wavelength.
