Applications of Euler-Lagrange Equation

AI Thread Summary
The discussion revolves around challenges in understanding Lagrangian mechanics, specifically Fermat's principle and the Euler-Lagrange Equation. A user seeks resources for worked examples to aid in grasping these concepts. Recommendations include the Schaum's series on Lagrangian Dynamics as a valuable resource for example problems. The importance of practicing problems independently for better comprehension is emphasized. Overall, the conversation highlights the need for additional learning materials in physics.

hey, In my physics class we are now learinging beginging to learn about lagrange ion mechanics and I am a little stuck on the basics of it particularly fermat's principle (dealing with light travel) and applications of the Euler-Lagrange Equation, I can't seem to get many of the problems at the end of the chapter, does anyone know a website or something that has a few worked out examples on how to do these?

thanks

If you are looking for example problems, I would say the best source other than online sources I don't know of would be the Schaums series on Lagrangian Dynamics. They cover many different examples. Of course the best way to learn is to do them yourself!

Good luck.
 

Thread 'Off resonance driving of a MW/RF cavity'

Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
