\varLambdaThe capital Greek letter Lambda, represented as \varLambda in LaTeX, is often used in mathematics and physics to denote eigenvalues in linear algebra, wavelength in physics, and various other constants or variables in different scientific contexts.
Matrix equation involving eigenvalues
A \varLambda B = CDe Broglie wavelength formula, where \varLambda is the wavelength, h is Planck's constant, and p is momentum.
\varLambda = \frac{h}{p}Wien's displacement law, where \varLambda_{max} is the peak wavelength, b is Wien's displacement constant, and T is the temperature.
\varLambda_{max} = \frac{b}{T}
