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

[@onirrapdivad]

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

[@abhinavtiwari2275]

you get the playlist of all related lectures at the official website of NPTEL

Great explation, each and every thing is explained in detail...Thanks a lot sir

[@shrutivashishth541]

Respected sir, This was very helpful. Thank you so much for these lectures 🙏

[@SOURAVMONDAL-xk7sv]

Sir Very Good Explanation

What a explanation.thank you

Thank you!!

Did you get rich from this? It's my share aswell. I knew it too. Thank you for sharing brother Namaste 🙏

E= Eo Sin wt, like that is mentioned in some text... is it cos or sin?

[@HimanshuSharma-xn6uc]

You can convert it into cos

[@amogh5427]

Sin or cos doent matter.

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

[@James-hl7vn]

Could you tell me the timestamp?

[@aerodynamico6427]

@@James-hl7vn Don't bother. A guy who thinks the wavelength changes but not the frequency knows as much physics as a doornail.

[@surelynottrue3894]

@@aerodynamico6427 You are ignoring the fact that the speed of light changes with the medium. Not so good to shoot down a replier this fast, is it?

[@milaanpatel4997]

@@surelynottrue3894 At the end of the video, the professor already told us that it is just a simple classical approach that doesn't account for quantum effects. The original commentor should not act like a headless chicken.

[@ayaskkantdixit1774]

this is the best "quantum" in the comment section

[@lifelessons1346]

How we identify light is either scattering or transmitted?

[@ayaskkantdixit1774]

based on wavelength

[@deep9277]

If its an angle with respect to the incident light

Why do the professors at IITs don't teach in the way they do on NPTEL? Watching at 2x speed feels as if I'm attending those IIT lectures at 0.5x. The same professors who are so poor at everything in lectures at IITs appear world class on NPTEL. Of course there are exceptions, but majority confirm to this trend.

[@rajajha9654]

what is the word mean optical analog plz tell me

[@James-hl7vn]

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. (Not from NPTEL and they most probably aren't reading these comments).

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 !
