Can a stationary, massive particle have a de Broglie wavelength?

Click For Summary
SUMMARY

A stationary, massive particle can indeed have a de Broglie wavelength, although it is negligible in practical terms. According to the de Broglie equation, λ = h/(mv), the wavelength (λ) is inversely proportional to the mass (m) and velocity (v) of the particle. Since a massive particle cannot be truly stationary above absolute zero, it will always have a non-zero velocity in some reference frame, leading to a very small wavelength. This discussion clarifies that while the concept holds, the implications for macroscopic bodies are minimal due to their large mass.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with the de Broglie equation
  • Basic knowledge of wave-particle duality
  • Concept of reference frames in physics
NEXT STEPS
  • Study the implications of wave-particle duality in quantum mechanics
  • Explore the de Broglie wavelength for different particle masses
  • Investigate the effects of temperature on particle motion and wavelength
  • Learn about reference frames and their significance in physics
USEFUL FOR

Students and professionals in physics, particularly those focused on quantum mechanics and wave-particle duality, will benefit from this discussion.

Quick question
Can a stationary, massive particle have a de Broglie wavelength? I thougt not but there is a question that doesn't state a speed. I think it might be incorrect.

Cheers

There's no such thing as a stationary sub-atomic particle above absolute zero. For a macroscopic body you can always find a reference frame in which it is moving. But that does not answer your question ...

Hey Swain ... Yes Massive Particle have de Broglie wavelength...But it is very less to compare because According to de broglie Equation lambda=h/mv
wave length of the wave is invresely proportional to the mass... so when the masss of the particle increases its wavelength decreases comparitively
