thanks, but thats a little too complex for me

I'll try to find something a little simpler.

Bragg's equation (nλ = 2dsinϑ) links diffraction spots (visible reality) with the underlying crystal structure (invisible reality) and can be easily visualized with a standard textbook picture.

Bragg's equation-very important in X-diffraction studies.

If more info is needed, please go to Google, or Wikipedia for a simple explanation.

Be sure you know what the symbols are in this equation.

From wikipedia:

nλ = 2dsinϑ

where

* n is an integer,
* λ is the wavelength of x-rays, and moving electrons, protons and neutrons, ( lambda )
* d is the spacing between the planes in the atomic lattice, and
* θ is the angle between the incident ray and the scattering planes
( theta )

In case you don't know the Greek alphabet, I've included the above definitions for your info.

Go to Wikipedia, plug in " Braggs equation ( or law ) and you'll get a summary. Get yourself a high school physics book and look of this equation.


This equation is important in various fields of Biology and Medicine ( Opthalmology ), for example.

thanks a lot! this helps a lot! I'm sure to ace the project now, thanks

Goodie!
