wavelength of matter waves in quantum mechanics

Propagation of de Broglie waves in one dimension – real part of the complex amplitude is blue, imaginary part is green. The probability (shown as the color opacity) of finding the particle at a given point x is spread out like a waveform; there is no definite position of the particle. As the amplitude increases above zero the slope decreases, so the amplitude diminishes again, and vice versa. The result is an alternating amplitude: a wave.

Playing a crucial role for the wave-particle duality in quantum mechanics.

Defining Formula: $λ \equiv \frac{h}{p}$
$h$ symbol represents Planck Constant
$λ$ symbol represents de Broglie Wavelength
$p$ symbol represents Classical Momentum
