    Please listen very carefully, folks. You can waste your time reading any text or watching any video, introductory or otherwise, on blackbody radiation, but this one is the very best. Don't waste your precious time looking at anything else. This gentleman is the very best. This is not meant to be a criticism of other authors/presenters/professors. No. But, there are some people - very few indeed - whose knowledge and depth of understanding is such that they can communicate the fundamentals and even complexities of very difficult subjects in a concise and yet thoroughly understandable manner. This gentleman is one of those people. God bless him for he has blessed us!!!

    Thank you ! For the first time I understood Planck's idea. It seems to me that this is even easier to explain if we say that with increasing frequency, the energy per degree of freedom is greater, but the number of degrees of freedom themselves are getting smaller and smaller, so the density of energy tends to zero. And in the classical case, the number of degrees of freedom of the electromagnetic field did not decrease with increasing frequency.

    love your lectures and I think they're a great supplement to my classes. I have one question though. I plotted the planck energy distribution using desmos to see a qualitative graph and played with the constants a bit. I can never get a positive concavity for low frequencies which is how you drew your graph. The exponential is overpowering the quadratic. Going back through your video I noticed that you also have a dv in the expression, though. Is this an infinitesimal? How do I interpret this and is this why I cannot reproduce the correct shape?
    thanks for the video

    I finally get it. The ultraviolet catastrophe happens on the right side of the graph. Previously I thought it happened on the left because I thought the x-axis was wavelength, not frequency.

      @@UmarFarooq-hs8iu ionization of what? As temperature increases you get vibrational modes that release electromagnetic radiation in the form of black body radiation that follows Planck law. At some point the energy will be sufficient to release electrons from the atoms (whatever the material of the black body is). What is the signal for this energy in the Planck curve? Or is the Planck curve only valid for energies below the work function?

      Possible values of energy is in Quantum mechanics is not zero as it violates very important principle amd also n can't be 0 it's minimum value is 1 not 0 so there is no zero energy in Quantum mechanics..
