Which of the following has the longest de Broglie wavelength if they are moving with the same velocity?

Options

  1. ANeutron
  2. BProton
  3. Cparticle
  4. D-particle

Correct answer

D. -particle

Step-by-step solution

de Broglie wavelength = h m v or 1 m (when v is constant) As m_ >m_n>m_p>m_ _ < _n < _p < _ Therefore, -particle has the longest de Broglie wavelength.
