De Broglie Wavelength Simulation

De Broglie Wavelength Simulation

This simulation demonstrates the de Broglie wavelength of electrons accelerated through different potentials. The wavelength is calculated using:

λ = h/p = 1.227/√V nm

Where V is the accelerating potential in volts. In the example: 1.227/√100 = 0.123 nm (X-ray range).

Results:

De Broglie wavelength (λ): 0.123 nm

Electron momentum (p): 5.40 × 10⁻²⁴ kg·m/s

Calculation: 1.227 / √100 = 0.123 nm

Wavelength Comparison:

X-ray range: ~0.01-10 nm

Visible light: ~400-700 nm

This electron's wavelength is in the X-ray range.
