How does wavelength change with speed?

Click For Summary

Discussion Overview

The discussion centers around the relationship between the speed of a particle and its wavelength, specifically in the context of the de Broglie wavelength equation. Participants explore whether increasing speed leads to an increase or decrease in wavelength, with a focus on the implications for macroscopic objects like a baseball.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses confusion about the relationship between speed and wavelength, suggesting that faster particles might have larger wavelengths, but questions this understanding in light of the de Broglie wavelength equation.
  • Another participant confirms that the de Broglie wavelength decreases as momentum increases, which is consistent with the equation λ = h/mv.
  • A later reply reiterates the point about the wavelength getting shorter with increased momentum, indicating agreement with the previous statement.
  • One participant poses a question about the wavelength of a baseball, indicating curiosity about the practical implications of the discussion.

Areas of Agreement / Disagreement

Participants generally agree that the de Broglie wavelength decreases as speed increases, but there is initial confusion regarding this relationship. The discussion reflects a mix of understanding and uncertainty about the implications for macroscopic objects.

Contextual Notes

The discussion does not resolve the implications of the wavelength of macroscopic objects like a baseball, leaving the practical application of the de Broglie wavelength in this context unclear.

Who May Find This Useful

Individuals interested in quantum mechanics, wave-particle duality, and the implications of the de Broglie hypothesis for both microscopic and macroscopic objects may find this discussion relevant.

I thought I heard the fact that when you make a particle faster it's wavelength get's bigger, and if we accellerate a baseball enough it's wavelength goes visible? but is that just a misunderstanding and opposite... because one can see in the broglie wavelength equation:

λ = h/mv that obviously as v(velocity/speed) increases... the wavelength becomes smaller... right? wasn't it all just a misunderstanding on my half?

UH ... what is the wavelength of a baseball?
 
Yes, the de Broglie wavelength gets shorter as the particles momentum increases.

ah just wanted to make sure, thanks
