Answer
λ (lambda) is the 11th letter of the Greek alphabet, written in lowercase. In physics, it's the standard symbol for wavelength. The uppercase version (Λ) is used for different quantities. Lambda appears frequently in scientific notation because Greek letters provide a universal symbolic language that transcends language barriers, making scientific communication more efficient and reducing confusion with other variables.
