Diffraction Patterns

Postby Amina Durrani 3G » Sun Oct 13, 2019 12:13 pm

In lecture we talked about how light (waves) in general show diffraction patterns and then we used the example of and x-ray passing through a crystal, can someone clarify how this example shows diffraction patterns?

This example shows diffraction patterns because the x ray is being or split when it goes through a crystal. The beam is going to enter at one angle, and exit at another.

X-ray passing through a crystal demonstrates diffraction because the wavelengths of the x-rays are so small that react with the crystal to produce unique interference. The waves bend around the medium and produce the phenomenon of diffraction.

The diffraction patterns arose because of measuring constructive and deconstructive interference when waves were passed through two holes in a barrier. These holes allow for the wave to interact with itself and produce the constructive and deconstructive interference patterns which can be measured to find a diffraction pattern. When passing an x-ray (or electrons) through a crystal, the waves are split and able to interact with themselves in order to produce these interference patterns in order to find a diffraction pattern.
