Question

Quizplus · Accepted Answer

The wavelength of an electron can be calculated using the de Broglie equation, λ = h / (mv), where h is Planck's constant (6.626 × 10^-34 m^2 kg / s), m is the mass of the electron (9.11 × 10^-31 kg), and v is the velocity of the electron (3.66 × 10^6 m/s). Converting the mass of the electron to kilograms and plugging in the values, we get λ = 6.626 × 10^-34 / (9.11 × 10^-31 kg * 3.66 × 10^6 m/s) = 1.99 × 10^-10 m.
