    Brilliant explanation! Personally, I find your style to be the most intuitive on this platform. Very concise with interesting side notes. Thank you for posting

    This is great. You should make a playlist of all the related lectures and embed a link to the playlist in the description.

    how can you say that the wavelength of the transmitted light will not change because as far i know when ever the light travels from on medium to another medium the wave length change only the wave no and frequency remain constant plz reply to my question

    what is the word mean optical analog plz tell me

    • @James-hl7vn
      @James-hl7vn 3 года назад +4

      So, for a lot of phenomena in optics, there is a similar phenomenon in the quantum world and vice-versa. For example, you have light interference and diffraction in optics and you have electron interference and electron diffraction in quantum mechanics. These are the quantum analogues of the similar phenomenon in optics. Raman thought that if Compton scattering is seen in the case of electrons in quantum mechanics, there might be a similar phenomenon in optics too(an optical analogue of Compton scattering). This is what professor meant by an optical analogue.

    Auflichtspektroskopie hört sich zwar schön an , nur was entsteht bei Auftreffen auf feste chemische Verbindungen
    Doch eher streulicht . Und worauf ersterckt sich die Erkenntnis auf einige Verbindungen
    die man durch FArbrealtionen vund chemische Farbverbindungsreaktionen 10 x besser sieht
    als vermischte Streuung ? und vieleicht bei Bedarf eher mit dem Mikroskop ganzheitlich Detail geht.
    Bei ganz anderer morphologischer Fragestellung . Hier die Gesamtfloureszenzfähigkeit
    einer Zelle zu berechnen ist zwar bunt und poppig aber eher ein Windei ohne präzise konkrete Probe
    die genauso genau untersucht wird und verschiedenen Einzelanalytischen Verfahren unterzugen wird ?
    Also ein Probe und viele wohlüberlegte präzise Untersuchungen und nicht hundert Proben
    zusammengepatzt und nicht noch mehr ungenaue Verfälschungsverfahren zur bunten Farbtombola
    ohne präziser Herausarbeitung der jewiligen systematisch angeordneten Fragestellung !
