J-space Calculations: Sources & Learning

[Piano man]

Hi,

I'm currently studying my Quantum Mechanics notes from college last year and I've got to the bit about j-space calculations. The slide is very scant on details and google isn't yielding anything on this either.
I would skip it but it seems important for deriving expressions such as Energy $$E(\lambda)d\lambda =k_b T\left[\frac{8\pi L^3}{\lambda ^4}\right]d\lambda$$ and the energy density in a cavity $$u(\omega)d\omega = \frac{\hbar\omega^3}{\pi^2c^3}\frac{1}{e^{\hbar\omega/k_bT}-1}d\omega$$

Does anyone have any good sources for learning more about j-space?

Thanks

for your post! It's great to see someone actively engaging with their studies and seeking out additional resources for understanding difficult concepts. Here are some suggestions for learning more about j-space calculations:

1. Check your textbook or lecture notes: Sometimes, the best resource for understanding a concept is right in front of you. Make sure you thoroughly review your textbook or lecture notes to see if there is any additional information or examples on j-space calculations.

2. Look for online lectures or tutorials: There are many online resources available for learning about quantum mechanics and j-space calculations. Look for lectures or tutorials from reputable universities or organizations, such as MIT OpenCourseWare or Khan Academy.

3. Consult with your professor or classmates: Your professor and classmates are valuable resources for understanding difficult concepts. Don't be afraid to reach out to them for clarification or to discuss j-space calculations together.

4. Visit your university's library: Your university's library likely has a variety of resources, such as textbooks, journals, and articles, on quantum mechanics and j-space calculations. Take advantage of these resources to deepen your understanding.

5. Attend a workshop or seminar: Many universities and organizations offer workshops or seminars on quantum mechanics and related topics. These can be a great opportunity to learn from experts and ask any questions you may have about j-space calculations.

Remember, understanding quantum mechanics and j-space calculations takes time and effort. Don't get discouraged if it doesn't click right away. Keep practicing and seeking out resources, and you'll eventually master this concept. Good luck!
