I have tried to explain here... but if you want video on that do mention... First you need sample of known concentration Then get absorbance data for that, from here you get a calibration curve absorbance vs concentration... Now take unknown conc sample and get the absorbance, now the corresponding value of conc from the calibration curve will give you the result.
We have to find the both band gap direct and indirect one, by changing the value of r in tauc relation. The gap value which is less in magnitude is the main transition.
Nice explaintion explain Dielectric analysis sir
Good 👍 Bhaiya
Good bhaiya
If you are taking UV-DRS data instead of anborbance then how to pli? In case of solid sample, how to take the thickness
Please tell ma how to decide n from wavelength and absorbance data???
👌👍
👌🏻👌🏻👌🏻
Please tell me how to decide which peaks correspond to which transition :( ?
Is it ok not to involve 2,303 factor while calculating band gap?
You first said for direct band gap n=1/2 but later on you can use this for indirect kindly clearify it?
Even though its late, 1/2 is for indirect.
plz what is the link of the program ? thank u
The music is distracting !
How to find concentration using this uv data?

How we know the type of transition indirect or direct?

where is 2.303 multiply?
Why u use background sound yar..
Actually when i record there is small disturbance... So to cover that i prefer to use background music...
Does this create too much distraction?
@@PHYSICSINSIGHT yes
@@PHYSICSINSIGHT this is normal excel sheet or any special software
Origin: its a graphing software
this music in the background dost not let us clearly hear the speaker....................
