Solved Problems on Bragg's Law

[@BeingAdi_18]

A X-ray of wavelength λ when incident on the (101) plane of a cubic lattice with lattice constant a produces first order Bragg's reflection at 0=30° (grazing angle). Suppose that lettice is compressed along the 3-axis so that lattice parameters along the x and y axes remain the same while the along the 3-axis become a/(sqrt(3)) * The first order reflection for the (101) plane of the compressed lattice occurs at-
A. 30 degree
B. 15 degree
C. 45 degree
D 60 degree

For 1st case d=a/√2
For 2nd case d=a/2
As sin@=n lambda / 2d
So sin@1/sin@2=d2/d1
On solving we get
Sin@=1/√2 so @=45 degree

In the x-ray diffraction for tantalum powder, the following angles were obtained using radiation of wave Length 0.15406nm 19.6,28.1,35.1,41.5,47.7,54.1,54.1,60.8,68.9.
Find, I,)the corresponding lattice planes.
ii)the lattice type.
ii) lattice parameters.
Plz help me mum, am grateful for your lecture.

So when h²+k²+l² is 2 what will be the milner index

[@SatyamSingh-u7n]

1 1 0 or 1 0 1 or 0 1 1 or 1bar 1bar 0 or 1bar 0 1bar or 0 1bar 1bar all are possible

How did you find lattice parameter using the formula for Simple cube but here we have to deal with FCC

Miss In the second question it says in the question 2nd order but you take n as 1. Why?

Calculate the Bragg angle if (111) planes of a cube (a = 3.57 A) crystal are exposed to X-rays (wavelength - 1.54 Å).
