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
