Expand description

A lightweight matter-wave wrapper stored by momentum magnitude.

Fields§

§momentum: f64

Momentum magnitude in kilogram meters per second.

Implementations§

Source §

impl MatterWave

Source

pub fn from_momentum(momentum: f64) -> Option<Self>

Creates a matter wave from a positive finite momentum magnitude.

Source

pub fn from_mass_velocity(mass: f64, velocity: f64) -> Option<Self>

Creates a matter wave from mass and velocity magnitude.

§Examples

use use_quantum::{MatterWave, PLANCK_CONSTANT};

let wave = MatterWave::from_mass_velocity(2.0, 3.0).ok_or("expected valid inputs")?;

assert!((wave.wavelength().ok_or("expected wavelength")? - (PLANCK_CONSTANT / 6.0)).abs() < 1.0e-12);
