Electron's Momentum (`lambda`)

The Momentum of an Electron calculator computes the momentum based on the wavelength of the electron and Plank's Constant

INSTRUCTION: Choose units and enter the following:

• (λ)  Wavelength of Electron

Momentum of Electron (Δp): The momentum is returned in grams-meters per second (g·m/s)

The Math / Science

The Electron's Momentum is found using the following formula: 

    Δp=(2h)/λ 

where:

• Δp = Electron's Momentum
• h = Plank's constant
• λ = wavelength
