Bragg's Law in physics provides the condition for plane waves. It gives a definition of the relationship between the spacing of the atomic planes in crystals and the angle of incidence wherein maximum reflection of electromagnetic radiation is produced....
Briefly describe what the Bragg equation relates. What information do we get from (i) a formula, and (ii) an equation? Explain the Henderson-Hasselbalch equation. What is it used for? What information do we get from a formula? From an equation?
Everything But The Girl and The Smiths had a wunderkind and it is named Belle & Sebastian. Erasmos Carlos, “Carlos, Erasmo…”—I’m a huge fan of Tropicalia, but had never encountered this gem from 1971. Erasmos Carlos was right in the center lane of the zeitgeist on this one. ...

The computation of a powder diffraction pattern via Debye equation involves all interatomic vector lengths; these are of order N2, where N is the number of atoms. This is clearly impossible except in few cases. However, a careful analysis shows that it is possible to proceed in two ...
on Al2O3(1120) and Nb film on MgO (111) The interplanar spacing d of Nb (110) can be obtained from the Bragg's law: 2d sin(θ) = λ (1) where λ = 1.5406 Å in this experiment. The peak position of Nb(110) in experimental plots is calibrated by dif- ...
3 The initial acceptance of spin as a property of the electron was in no way connected to any independent measurements. And, as we shall see below, the Stern–Gerlach experiment, which is typically understood as the first measurement of spin, was not really a measurement of electron spin at...

Standard Deviation Equation, Formula & Examples from Chapter 13 / Lesson 4 217K The standard deviation of a data set is a measurement of how close, in aggregate, its values are to the mean. The baseline from which this distance is measured is the mean o...
In addition, when the spacing of crystal layers, also known as path difference, is equal to some integer factor of wavelength, constructive interference occurs. This can be mathematically described by the following equation, {eq}\begin{align} n\lambda = 2d\mbox{sin}\theta \end{align} {/eq...
