He never flex his physics knowledge but always makes us understand in simplest way possible.

We are very lucky to have you in india🌝🌝

i was studying but this seemed more important

Sir, Happy Birthday!🍰 Concepts of physics is a real blessing for all the physics enthusiasts. On this auspicious day, I'd like to thank you for the book. Long live sir! Just need your blessings to succeed!

You are an inspiration sir, I watch all your videos, I am pursuing engineering and I love the way you teach.

Sir Aap hamesha ham sab ke hridya me raaj kariyega.We all are motivated by your love for physics.

I love his smile very much

Sir aap jasa teacher arboo me ek hote hai It means aap jase sirf 7 hi teacher hai, jinme se ek hum sab ke pass hai, sach me hum bhuot lucky hai🤗😊

Excellent work doing for us !! Thank you sir, There are very few such person on the earth who are always ready for supporting others , Thanking you sir

मैं अपने आपके को गर्व महसूस करता हूं कि आप जैसी प्रोफेसर से पढ़ने का सौभाग्य प्राप्त हुआ 👍

Kya bat h itne saral aur sundar tarike sai concept ko clear kar diya mere toh concept clear hi nhi ho rha tha. thank you God ki mujhe apki video mil gyi. Thank you so much sir. And thank you Prashant for asking such a beautiful question.

You are the most humble person 😊🙏

The aperture of the lense (the curvature of lense surface) is part of a hypothetical circle, called circle of curvature & its radius is known as radius of curvature. As you increase or decrease the size of aperture the lense becomes thin or thick, its curvature decreses or increases accordingly and hypothetical circle that generates from this curve is of biggeer or smaller size with its radius of curvature large or small. Then use the relation R = 2f & imagine yourself how focal length will vary. लेंस का एपर्चर (लेंस की सतह की वक्रता) एक काल्पनिक वृत्त का हिस्सा है, जिसे वक्रता चक्र कहा जाता है और इसकी त्रिज्या को वक्रता की त्रिज्या के रूप में जाना जाता है। जैसे ही आप एपर्चर के आकार को बढ़ाते या घटाते हैं, लेंस पतला या मोटा हो जाता है, इसकी वक्रता कम हो जाती है या तदनुसार बढ़ जाती है और काल्पनिक वक्र जो इस वक्र से उत्पन्न होता है, बड़े या छोटे आकार का होता है, जिसकी वक्रता बड़ी या छोटी होती है। फिर संबंध R = 2 f का उपयोग करें और कल्पना करें कि फोकल लंबाई कितनी भिन्न होगी।

सफलता का एक मूलभूत नियम है कि आप अपनी गलतियों के साथ-साथ दूसरों की गलतियों से भी सीखते चले और आगे बढ़े ✨😊😊🔥🔥.

It shows ur generosity sir ..........

Sir you made me fall in love with physics...... thank you🙃

Every student requires a teacher like you sir

Aapse bhut inspiration milti h guruji...

Thank you, sir, you cleared my doubt.

Happy birthday sir! Aaj se 15 saal pehle 2006 me sir humne aapki kitaaben padhni shuru ki thi... Aaj hum Engineer ban gaye hain... Sir hum kachhe bacche the aur khud par yakeen bhi kam hi tha... Lekin fir bhi aapke sawaalon se joojhte rehte the... Aapki baaten sunna, padhna sunna bahut achha lagta hai sir... Please KZfaq channel par ya kisi bhi platform par humse jude rahen aur hum sabko sikhate rahen! Lots of love to you and physics taught by you, sir!

Thank you so much Sir!

BEST EXPERIENCE TEACHER OF INDIA....👍👍👍👍👍

Sir mujhe apki dekh bhut inspiration milti hai ,apke videos dekhte hi mere andar electric currents flow krne lagte hai 😂🔥🔥

Thank you so much sir 🎉

*Best physicist and most humble teacher in India* Hit like if you agree

Thank you sir to motivating me for self study.

Thank you sir we need your blessings.mere question ka answer mil gya

Love you sir.😘😘 Great explanation..🙂🙂

Thank you sir you are so great 😊❤

I am not in cls 10 th but steel watching👀 😁😁😁😁big fan sir

Wonderful explanation!

Who really waited for sir video ❤️❤️❤️❤️

*Best teacher I ever saw*

Thanku so much sir ji .. Ye question bhi tha🙏

Sir you are the bestttt!!!!!! Please make a full physics series for class 10

I was very confused that why the focal length increases when the lens becomes thin...but finally got it😭💕

Well done 👍 sir you’re genius

really love u a lot sir ji.....🙏

Excellent explaining sir ji

Thank You Sir

Very genius teacher 👍👍

Positive work done decreases the internal energy and positive heat increases it. --- these lines are given in your book concept of physics 2--Page 50 Please explain it, sir. Thank you, sir

Sir muje apaka bat karane ka tarika bahut achcha lagata hii

Hello sir bending of cyclist me normal ka direction surface ke perpendicular kyu nahi hota. Along cyclist Kyu hota hai?

HC Verma ❤

Sir please explain the passing of current through resistor and its increase and decrease in magnitude

Pranam SIR 🙏🙇

Happy Birthday Sirji 🙏

Thank you sir 🙏🙏

To Be The best you need the best

Sir, I have a pretty intriguing way to visualise it, do let me know if it is correct. A lens can be thought of as a collection of prisms, from top to bottom, and a slab in the middle. The tendency of a prism is to bend incident light as per its structure and orientation, whereas when the light passes through the optic centre, it is essentially passing through that part of the lens which we have thought of as a slab, so it goes undeviated, passing through the centre of the slab of an infinitesimally small thickness.

Sir, jab compound plates se refraction hota hai, tab keu 1st face ka angle of incidence last face ki angle of refraction se equal hojata hai?

Please explain how to draw focus point in ray diagram of convex and concave lens

Hope you live millions of year

Sir , U object distance and f focal length ko dekh kar image ka nature aur details bats skte h . Ye bata dijiye sir

Love and respect to u❤️❤️❤️❤️

Sir aap moving coil galvanometer pr bhi ek video upload krdo

Best guru ji 🙏🙏🙏🙏🙏

sir jab mirror me Ray's actually me bahar meet karti hai to hm undar kyo dekhte hai

Thank you sir

Sir I have a question In two triangle if corresponding angles (by AAA rule) are equal then triangles are similar, But why they are not congruent?

why on rubbing rod is electrified and not electrified on coming contact ?

very nice session sir

Sir why the velocity of the image becomes double the velocity of object in case of plane mirror

Sir could you please briefly explain about how to point the focus in convex and concave lens in english

Thanks sir 😊🙏🙏

Sir you are brand in globe

sir i request you to discuss my following point on collision:- 1. is it necessary that after perfectly inelastic collision bodies will stick together and move with same velocity or it is like that the velocity along line of impact will be same ,no matter bodies stick together or not.

Sir I will be eagerly waiting for your answer...

Hlo sir aapse questions kon se platform pr puch skte h???

Nice explanation

Sir I have doubt Which lens we use in projector Gaurav

Sir please explain why the rays passing through optic center don't deviate

Can someone please tell me that how they send their doubt questions to sir🙏🏻

Sir aap kab livestream karaoge

Sir I am in class 12 now I am using your book hc verma concepts of physics. Sir please 🙏🙏suggest and please make a short video how to wisely solve numericals .I hope you will definitely consider on it sir please

Sir can you please share your experiences of creating a book for class ix and X students.

Sirji focal length is the distance between the focus and pole

Sir please explain why it is E=mc^2?

Sir , how is it applicable with concave lens

Sir what will be focal length of convex lens if it dip in two muadium

Sir this is Anshul Ghosh from Pune, Sir could you please explain viscosity to me in brief, one of your biggest fans. Thank you.

Dhanyad sir

Sir why in transformers not use capacitors

Sir Kya light rays lens ke andar hi reh skti h

Sir, please do explain us, The Cartesian Sign Convention! Since, I'm facing much doubts and confusion regarding the same!

1/f = ( mu-1) ( 1/R1 - 1/R2 ) This is lens makers formula... So if we change radious of curvature ...so focal length will also change💟💟

sir convex lens ke dono focal length same hote hai ??

Sir why with more angle of incidence there will be more bending??

Sir namaste 🙏 Can you please tell that what is the exact definition of CHARGE how can we define CHARGE not it's types +ve Or -ve DEFINITION OF CHARGE

I have met him when I went to ismf in iit patna❤

Sir please make a video on orthogonal coordinate system

Sir I have a question that If I take a simple pendulum to space and another one in earth's atmosphere neglecting air resistance . So both will have same oscillation if they are started at the same time ????? And is there will be energy lost in case of simple pendulum in space and it will oscillate endlessly ??? And Sir I am preparing for IIT 2022

Sir gauss theorem pe Ek video baniye... Love and respect from West Bengal
