Furthermore, I just want to make sure, for the following two rules: Reflection Across Y-Axis. $(x,y)\to(-x,y)$ Reflection Across X-Axis. $(x,y)\to(x,-y)$. Do they have formal proofs or do we just prove them by visualizing where a point ends up to be on a cartesian plane?
A reflection is a linear transformation on the plane with eigenvalues $\pm 1$ and orthogonal eigenvectors. The line spanned by the eigenvector with eigenvalue $1$ is called the reflection line, line of reflection, or mirror line; the line spanned by the eigenvector with eigenvalue $-1$ is called the normal line.
Reflection about the x-axis; Reflection about the y-axis; Vertical shifting or stretching; Horizontal shifting or stretching; Tell me if I'm wrong, but I believe that in any function, you have to do the stretching or the shrinking before the shifting. But where do the reflections fall in this process?
The process of reflection of a shape S about a line L is very simple. For every point of S draw a line meeting L perpendicularly. Then extend this line equally further and stop. The point where you stopped is the reflected image of the point you started with. Do this for every point of S. Alternatively think of the plane as a sheet of paper.
In this sense, the reflection principle is a direct consequence of the fact that the reflected process $(W_t)_{t \geq 0}$ is a Brownian motion - justifying the name of the result. Share Cite

The diffraction peaks labeled in Figure 3.33 correspond to the reflection rules for an FCC metal (h,k,l unmixed, as shown in Table 3.4). (a) What would be the (hkl) indices for the three lowest diffraction-angle peaks for a BCC metal?

(10 points) (b) Calculate the diffraction angle (20) for the first three peaks in the diffraction pattern of a-Fe powder (which is a BCC metal) using CuKu-radiation (λ=0.1 542nm).
