We are matter wave
All matter could be said to have momentum as it moves. The momentum however is inversely proportional to the wavelength. So since your momentum would be large normally, your wavelength would be too small to measure for any practical purposes. An electron, however, due to its mass would have a very small momentum relative to a person and thus a large enough wavelength to measure thus producing measurable results.
This led us to start using the ElectronMicroscopes rather than traditional
Light microscopes.
The electron microscope
After the specimen is prepped. It is blasted by a bean of electrons. As the incident electrons strike the surface, electrons are released from the surface of the specimen.
The deBroglie wavelength of these releasedelectrons vary in wavelength which can then be converted to a signal by which a 3D picture can then be created based on the signals captured by the detector.
