- to test their wave nature a diffraction grating with slits 10 -10 m<br />
apart would have to be used; they used crystals in which the<br />
atoms were spaced about 10 -10 m, instead of a diffraction<br />
grating<br />
- the atoms in the crystal acted like a diffraction grating and an<br />
interference pattern was observed<br />
- the interference pattern, however, was in three dimensions<br />
instead of two dimensions seen in Thomas Young's<br />
experiment<br />
- this 3-D image was more complicated to study, yet still<br />
effectively proved the wave nature of X-rays<br />
- after the discovery of X-rays, there was a great wave of<br />
excitement from the scientific and business community<br />
- hospitals used X-rays for medical tests, industry used X-rays for<br />
viewing the inner structure of materials; for example,<br />
engineers used X-rays to study welds and defects in<br />
structures)
