What is the wavelength of the matter wave associated with an electron moving with a speed of 2.5 × 10⁷ m/s? (m_electron = 9.11 × 10^-31 kg,h = 6.626 × 10^-34 J ∙ s) A)29 pm B)35 pm C)47 pm D)53 pm

Question

Quizplus · Accepted Answer

The de Broglie wavelength λ is given by λ = h / (mv). Substituting the given values: λ = 6.626 × 10^-34 J∙s / (9.11 × 10^-31 kg × 2.5 × 10^7 m/s) = 29 pm.
