Thank you sir ❤❤

Please STM py bhi ak lecture forward kryn 😊 scanning tunneling microscopy

revision completed

💯

Sir this is too much helpful thank you ❤❤❤

Sir this is too much helpful thank you ❤❤❤

Sir I needed your help for engineering drawing subject. Which channel will be helpful and any other resource if you have please provide me. I am in semester 2.

Very nice video cleared my concept even though I didn't study much prerequisites Thank you sir ♥️

😊

2025 batch plzz watch this it is very use full🙏

1:25

Thanks Skibidi Sir

Thank you so much sir..🙏🙏

why is he:ne ratio 10:1 it can be more for better laser?

Thank you so much sir 🙏

whats the point of sending the electron to 2nd excited state when it will eventually come in 1st excited state??i mean 2nd excited state is not metastable state so why bother excited the atom to 2nd one?

Very nice information sir. Thanks 🎉

Sir ji amazing lec 🎉

Hi sir in the above derivation taking Mu common would mean that both the film and the above medium have the same refractive index i.e., the light ray is travelling in the same medium ?kindly correct me if i am wrong

i shared you links to my college group because you are stunning

mic kaha hai? hein?

Thankyou very much sir These lectures help me a lot for preparing for exams Due to this lectures my today's physics exam gone very good

My paper is after 4hr and i am watching this video ...... its really helpful ... all concept is clear ... tysmmmmm

such a veryyy good explanation, I lernt something new haha. THANKS A LOT!!!

Awesome Content ❤

Sir,khaali aapki vajah se mera aaj ka Physics ka paper bahut accha gaya . Thank u so much sir

7:48 can we just take the ratio of both diameters and equate it to refractive index ?

25:26 me extrinsic semiconductor hoga na

Thanks

Sir provide notes also plz😢

sir how to calculate e power something

9:52

Sir u are a saviour 🙇🏻

Thank you sir Very easy to understand and helpful for last moment studies.

This is best physics lecture for all engineering branches

Is it necessary to micro meter to meter even all quantities are given in micro meter?

Sir u forget, who is the father of optical fiber he is indian and u didn't cover him

HENCE PROVED INDIAN TEACHERS R THE BEST

Thank you so much sirrr

please i would love to know the name of this book

Best lecture ever

Just awesome lecture sir

Best explanation❤

Sir which book have you referred

Sir really like your teaching But wouldn't it had been better if you first explained what is del operator and then teached (dellT) questions which you taught just before explaining del concept? If i am wrong Please correct me Btw love your videos Really helped me learn a lot Also sir i am also from kjsce vidyavihar

Thank you

Thanks a lot sir ❤
