Question

Quizplus · Accepted Answer

The de Broglie wavelength λ is calculated using the formula λ = h / (mv), where h is Planck's constant (6.626 × 10^-34 Js), m is the mass of the electron (9.11 × 10^-31 kg), and v is the velocity (7.90 × 10^6 m/s). Converting the mass to kg and substituting the values gives λ ≈ 9.21 × 10^-11 m.
