## De Broglie Wavelength
Louis de Broglie proposed that all matter has wave-like properties, with a wavelength inversely proportional to momentum.
### Formula
**lambda = h / p = h / (m v)**
- *h* = 6.626 x 10^-34 J s (Planck constant)
- *m* = particle mass
- *v* = particle velocity
This wavelength is measurable for electrons and neutrons, and is the basis of electron microscopy.

हल किया गया उदाहरण
Electron (m = 9.109e-31 kg) at v = 1e6 m/s.
- lambda = h / (m v)
- p = 9.109e-31 * 1e6 = 9.109e-25 kg m/s
- lambda = 6.626e-34 / 9.109e-25
- lambda = 7.274e-10 m = 0.727 nm
