如何计算De Broglie
learn.whatIsHeading
De Broglie wavelength describes the wave-like properties of matter. Every particle has an associated wavelength related to its momentum.
公式
The calculator applies λ = h / p where h is Planck\'s constant
分步指南
- 1Enter particle mass and velocity, or momentum directly
- 2The calculator applies λ = h / p where h is Planck's constant
- 3Results show the equivalent wavelength
例题解析
输入
m = 9.109 × 10⁻³¹ kg (electron), v = 0.1c
结果
λ ≈ 2.43 × 10⁻¹² m
Electron wavelength at relativistic speed
常见错误注意事项
- ✕Forgetting to convert velocity to momentum properly
- ✕Using wavelength formula without proper unit conversion
常见问题
Why don't we observe wave properties of macroscopic objects?
Wavelength is inversely proportional to momentum; massive objects have extremely small wavelengths, undetectable.
How does de Broglie wavelength relate to uncertainty?
It's connected to Heisenberg uncertainty principle; shorter wavelengths allow more precise position measurement.
