#research #physics/quantum # de Broglie Wavelength Equation The de Broglie Wavelength Equation solves for a particle's wavelength as a function of its momentum. $ \lambda = \frac{h}{mv} $ where: - $m$ is the mass of the particle - $v$ is the particle velocity - $h$ is [[Planck's Constant]] - and $\lambda$ is the wavelength of the moving particle.
