Application of de Broglie Equation

To calculate the de Broglie wavelength of an electron, use λ = h/(mv), where m is the mass of the electron and v is its velocity. For example, if an electron has a velocity of 2 x 10^6 m/s, the wavelength can be calculated using the known mass of an electron (9.11 x 10^-31 kg) and Planck's constant.
