Wavenumber is a measure of spatial frequency, defined as the number of wavelengths per unit distance, typically expressed in reciprocal centimeters (cm⁻¹). It is a crucial parameter in spectroscopy and wave mechanics, providing a direct link between the energy of a wave and its wavelength or frequency.

Wave mechanics is a fundamental aspect of quantum mechanics that describes the behavior of particles as waves, providing a framework for understanding phenomena at the atomic and subatomic levels. It introduces the concept of wave functions, which encapsulate the probabilities of finding particles in various states and locations, fundamentally altering classical notions of particle dynamics.

Wavelength is the distance between successive crests of a wave, typically used in the context of electromagnetic waves, sound waves, and other sinusoidal waves. It is inversely proportional to frequency, meaning that as the wavelength increases, the frequency decreases, and vice versa.
