Calculation Methodology

de Broglie Equation: λ = h / p = h / (m * v). Where h is Planck's constant (6.62607 x 10^-34 J s), m is particle mass in kg (electron mass = 9.10938 x 10^-31 kg), and v is velocity (m/s). Linear momentum: p = m * v (kg m/s).

Frequently Asked Questions

High-velocity accelerated electrons have de Broglie wavelengths in the picometer range (0.002 to 0.05 nm), hundreds of thousands of times shorter than visible light photons (~500 nm), virtually eliminating diffraction limits.
