Which of the following particles has the longest de Broglie wavelength if they all move with the same velocity $v$?
- A.Proton
- B.Neutron
- C.Electron
- D.Alpha particle
Show correct answer & step-by-step solution
Correct answer: C — Electron
Solution
The de Broglie wavelength is . Since the electron has the smallest mass among the given particles, it will have the longest wavelength for a constant velocity .
