  • Einstein Coefficients were developed by Einstein in 1916 to describe how atoms absorb and re-emit photons. We introduce these coefficients and derive the Einstein Relations between them using Bolzmann and Planck statistics. More material at: casper.berkele...

    The best video on UA-cam for Einstein's Coefficients. Your students are really lucky to have you as their professor. Thanks a ton.

    Nice explanation. Thank you for sharing this. This made it really easy to understand those previously mysterious Einstein coefficients. I kept coming across those with regards to radiative transfer and line shapes, but didn't really understand them.

    It was really well explained. I just didn't get the part why and how the initial ratio of A and B einstein coefficient was not compatible with the planck's equation. Can someone explain?

    • @mrutyunjayasahoo971
      @mrutyunjayasahoo971 2 роки тому +1

      because of the format of the equation. If A and B are intrinsic properties then the LHS &RHS must be of same form. That's the point Einstein noted and solved. Ig I understood your problem and answered clearly.

    • @spacejunk2186

      A and B are properties inherent to the geometry of the atom, so they cannot depend on Temperature. But in the first equation, they are.
