What Is the De Broglie Wavelength?
The de Broglie wavelength expresses the wave property of a moving particle. It is the foundation of matter-wave duality.
How is it calculated?
How Is It Calculated?
λ = h ÷ (m × v)
h = 6.626×10⁻³⁴ J·s.
- Enter the particle's mass and velocity.
Frequently Asked Questions
Why don't we see waves in everyday objects?
For large masses the wavelength is too small to measure, so the wave property goes unnoticed.
