OK, I have this homework problem that I need some help solving . The question is as follows:


Consider two events that take place at different points in the K system at the same instant t. If these two points are separated by a distance delta-x, show that the events are not simultaneous in K' (which has a relative velocity v) and find the time interval delta-t' between them.



I figure some of you have had courses where this material was covered in detail and have a firm understanding of how to derive the necessary formulas to prove the case. My teacher skimmed this material yet expects us to understand how to answer this question. I am starting to check various sources to figure it out, I just though it would help to get a little insight into other people's ways of solving problems. Thanks for any help you can provide.

Lorentz Transformations

Look up the Lorentz transformations, which provide a recipe for translating space and time measurements between moving frames.
 
Thread 'Need help understanding this figure on energy levels'
This figure is from "Introduction to Quantum Mechanics" by Griffiths (3rd edition). It is available to download. It is from page 142. I am hoping the usual people on this site will give me a hand understanding what is going on in the figure. After the equation (4.50) it says "It is customary to introduce the principal quantum number, ##n##, which simply orders the allowed energies, starting with 1 for the ground state. (see the figure)" I still don't understand the figure :( Here is...
Thread 'Understanding how to "tack on" the time wiggle factor'
The last problem I posted on QM made it into advanced homework help, that is why I am putting it here. I am sorry for any hassle imposed on the moderators by myself. Part (a) is quite easy. We get $$\sigma_1 = 2\lambda, \mathbf{v}_1 = \begin{pmatrix} 0 \\ 0 \\ 1 \end{pmatrix} \sigma_2 = \lambda, \mathbf{v}_2 = \begin{pmatrix} 1/\sqrt{2} \\ 1/\sqrt{2} \\ 0 \end{pmatrix} \sigma_3 = -\lambda, \mathbf{v}_3 = \begin{pmatrix} 1/\sqrt{2} \\ -1/\sqrt{2} \\ 0 \end{pmatrix} $$ There are two ways...
