A proton has five times the momentum of an electron. If the electron has a de Broglie wavelength λ, then the de Broglie wavelength of the proton is
A) λ.
B) 5λ.
C) λ /5.
D) 25λ.
E) λ /25.

Question

Quizplus · Accepted Answer

The de Broglie wavelength is inversely proportional to momentum. If the proton has five times the momentum of the electron, its wavelength will be one-fifth of the electron's wavelength, λ/5.
