DeBroglie Wavelengths
The wavelength associated with a particle can be calculated from:
You may enter values in any of the boxes. When you have finished entering data, click on the quantity you wish to calculate in the formula above. Wavelength values will be reconciled, but no further calculation will be done until you select which item you wish to calculate. Caution! This calculation is non-relativistic and accurate only for speeds much less than the speed of light. For speeds over a tenth of the speed of light a relativistic calculation should be used.
If you explore the wavelength values for ordinary macroscopic objects like baseballs, you will find that their DeBroglie wavelengths are ridiculously small. Comparison of the power of ten for the wavelength will show what the wavelengths of ordinary objects are much smaller than a nucleus. The implication is that for ordinary objects, you will never see any evidence of their wave nature, and they can be considered to be particles for all practical purposes. |
