1:03:36 there is a silent correction there. Ma'am actually forgot to put 'r' in that first orbital equation, although they corrected but it went unnoticed. So this is for those who were confused.
I was totally depended on your teachings for chemistry and physics through out my 12th and yesterday I gave my Physics and before that chemistry paper.... I gave an excellent performance more than my expections and that's only bcoz of you ma'am thanks a lot for making "SUCH VIDEOS FOR FREE "🥰🥰🥰❤️
i was Watching your lecture of dual nature of matter and was wishing that u'll upload lectures of atom and nuclie... and i am so happy to see this, thank u so much mam 💗✨
Chlo koii milla jo concentrate hoke dekh rha h purralecture wrna comment section me toh chutiye hi bharre h sirf..... ya toh bio walee h jinhhe maths aata hi nhi h😆😆
Thank you ma'am. Its a request plz upload 15th May - Semiconductors 16th May - Wave Optics 17th May - Electromagnetic waves 18th May - Nuclie 19th May - Full Term 2 Important Questions/TOPICS/PYQs revision of PHYSICS. Also if possible kindly upload TERM 2 biology and Maths remaining chapters videos that will help us
Appreciating your and your team's great efforts that in so less time you are doing everything you can and every concept is just crystal clear 3 out of 7 chapters √√ Thank you so much ma'am
Mam my father just respects you so much. He cant stop appreciating you and your team. It needs a lot of courage and needs a lot of hard work for creatinf long videos. Hats of to you mam. I thank god for giving us a teacher like you
👍👍👍👍👍 Thank you ma'am , Concept hua cristal clear .. Ma'am please upload a one shot of nuclei This is humble request from all student who are preparing for their exam through you videos..
Ma'am please Sare chapters complete kra dena aap 🙏. I'm your very old student and always dependent on you. 💓 Congratulations🥳 for 2 millions. This is the best learning platform. Concept always crystal clear #freehaiparbesthai 💕

It’s a request to record the other chapters also coz we are completely depend on u Ma’am 🥺🤧semiconductors wave optics nuclei we don’t need electromagnetic waves 🌊
Very nice lecture ma'am but i would like to suggest you TO USE BLACK BACKGROUND WHILE WRITING (ONLY) Because watching videos at night becomes very uncomfortable to eyes............. But the lecture is awesome ma'am. You are great ma'am
Ma’am, at 1:00:00 while solving the Bohr’s Radius you didn’t wrote the ‘r’ while finding ‘v’. You did add it in the last but students might get confused on where did the r go.
i'm watching this video live, relaxed eating my dinner , because mam's voice is sooo calming and she explains concepts soooo well!! literally the best teaching platform, mam please make a video on wave optics as well, i am very well sure many students are looking forward to complete their term 2 and are dependent on your teaching skills!!
Raosni mam ap last moment pr ek angel ki trha ho ek dum mst padhai hai padso mera exam hai or ap se Maine sre modern physics padh liya hai ache se thankyou maam❤❤❤🙏🙏🙏✨️✨️✨️
In topic Bohr's Radius formula of v² was : v²=Ze²/4×pi×Eo×m×r By this formula answer is coming correct but you have skipped r in this formula , still you wrote correct answer at the end.
Thank you so much mam for your great efforts I know we have very less time Mam meri apse request h jo syllabus delete hua h from CBSE please hame vo bhi karva dena becoz deleted syllabus bhi ayega hamare entrance exam me.
Dear Roshini Mam.... Thank you so much for this wonserful lecture...Lots of love and salute to your hard work and dedication.. We are eagerly waiting for this.. Next wait_ Ray Optics ....
Deleted Topic cbse 2024 Spectral Series, Bohr Model of Hydrogen Atom - derivation deleted, Line Spectra of Hydrogen Atom - qualitative treatment retained Deleted Exercises 12.3,12.11-12.17
At 1:01:37 r kaha gya?? V²=Ze²/4π.ε0mr hona chahiye na and 5:52 & 20:00 not radius but diameter of an atom is about 10^-10 and diameter of nucleus is about 10^-15.
Thankuuu mam for this amazing lecture....salute to ur teaching.... literally sare concept crystal clear ho gye....and also ur smile creates this lecture more interesting and fruitful...once again thanku mam
mam thomsons model of atom Heisenberg uncertainty principle De-Broglie’s hypothesis: Wave-particle duality for matter De-Broglie’s Explanation of Bohr’s postulate are not there in syllabus kindly clarify we are to do or not?
Thanks a lottt mam .....all concepts got cleared and there is no need of reading the physics book as u have mentioned all the concepts....... very grateful mam❤️
