De Broglie Wavelength Calculator
Calculate the wavelength of matter using de Broglie's equation
Method 1: From Mass and Velocity
OR
Method 2: From Momentum
h = 6.626e-34 J·s (Planck's constant)
Electron mass: 9.109 × 10⁻³¹ kg
Formula Used
λ = h/p = h/(mv)
Where: λ = wavelength, h = Planck's constant, p = momentum, m = mass, v = velocity
