Hi, How can eco-cooler works? The explanation of blowing with mouth are totally wrong, but I am curious aboud dynamic of air flow, if is possible to achieve measurable cooling Thanks

Hi, I know how to calculate density of states for both cases, but it is not clearly to me how I can go from 3D case to 2D. I have energy from infinite potential well for 3D $$E=\frac{\hbar \pi^2}{2m}(\frac{n_x^2}{l_x}+\frac{n_y^2}{l_y}+\frac{n_z^2}{l_z})$$ let make one dimension very small...

Yes

and I see from dispersion formula that each ω has two k, so what key will be inside the line, and how can I switch is for another one.

Hi, I have transmission line with dispersion relation ω=sin(kx), so then means that for one value of ω I have two values of k. I apply voltage with some frequency with is allowed to move in the line. First question is, how can I influence what k will be generated inside the line. The another...

sure, I am sorry, it is what I meant. not line but some broader peak

Hello, I read a lot at this forum about thermal radiation but still i have questions. Consider black body at some temperature T. It means that inside that body we activate many modes of quantum oscillators with some probability(Bose-Einstein) depend on temperature T. Now let's have some bulk...
