x ray diffraction การใช้

• I've done an experiment with x ray diffraction which were told the x-rays are at 2 frequency's and was wondering what an appropriate error in the wavelength would be . i can think to sources of error in the wavelength but i don't now how to quantify it . the two i thought of where the sources not quite emitting at the wavelength said, and the wave spreading between source and the crystal ( ie wavelength L ends up being several waves over L-delta L and L + delta L, i assume we used soft xrays though not sure if that helps or is true wavelengths given where around 0.1-0.2nm-- 137.205.79.218 23 : 53, 13 February 2007 ( UTC)
