Calculate the wavelength of an electron (mass = 9.109 × 10^-31kg)traveling at4.38 × 10⁶ m/s.

Question

Quizplus · Accepted Answer

The wavelength of an electron can be calculated using the de Broglie wavelength formula: λ = h / (mv), where h is Planck's constant (6.626 × 10^-34 m^2 kg/s), m is the mass of the electron, and v is its velocity. Substituting the given values, λ = 6.626 × 10^-34 / (9.109 × 10^-31 × 4.38 × 10^6) = 166 pm.
