what an inspiration you are

Sir aap idhar...

physics wallah u inspired me #don't became an audience 4 the world be a magician that I never forget in my life

[@RaviVermaAgra]

Hello Sir!!! 😂😃😃

[@jacobblack2544]

Both of you sir

[@haajmola5164]

You are the GOD of physics. sir mujhe physics aachi nahi lagti thi but you make my interest towards physics. thank you so much for giving us free education. we always pray for you. you are doing great job.

bhai. sir. ko kuch contribute. b kr do

[@umarsaid9589]

I know he is best teacher but GOD is only Allah Almighty

According to me, the topic was ununderstandable to them because they have no interest in physics. This teacher is god gifted. We salute you sir for your contribution to great knowledge.

[@alien8840]

best physics teacher ever !!!!!!☝☝☝☝

[@digvijaypattnaik5602]

sir the way you teach physics is really awesome,,,,!
sir please make special videos for Numericals too.
:-)

[@AnubhavSingh259]

+Digvijay Pattnaik There is a video for that.

[@digvijaypattnaik5602]

+Anubhav Singh Ohh thanks mate!

[@AnubhavSingh259]

Gud luck!

[@shoaibalishaikh9993]

no words to explain.......

[@jayprakashbind9142]

Very awesome explanation salute sir

[@harsh2770]

Sir please write a book.....You are extremely knowledgeable....

[@akaraze749]

Thank You so much Sir You cleared my doubt regarding reference logic THANK YOU SO MUCH .Love You Sir
And I cant still draw doted line like Walter Lewin Sir ..

[@ranjeet5806]

still cant*

[@theowner1971]

sir you great and i am glad to have you as a teacher

[@fahimmustaque1786]

Sir u are best teacher of physics.... 😅🏞🇮🇳😉🙁

[@nitantish]

sir why we are taking only "sin" ratio in snell's law why not "cos" or the other ratio

[@mineisovermir817]

same question bro

[@achintyagautam948]

Awesome sir....nice examples and explanation.....thank u sir

[@Parameswar_Ghosal]

Sir , if the angle of light ray refracted from medium 3 to medium 1 . so what will the derivation ........
Thank you sir for your physics lectures ................

[@RahulDas-wj2xh]

thank you sir,!!!! with give us free education which is very very high quality

[@VivekKumar-sh9yu]

Sir , you are one of the greatest physican of india .

[@ranjeet5806]

hizde phele dekh le kya bol rha hai *physician* hahahahah

[@luckytiwari5582]

Brilliant skill sir

[@yadvinderbansal4247]

Thankyouu so much sir god bless youuu infinitely😇😇

[@mumair3123]

Literally my senior and friend topped medical entrance exam known as ETEA in Pakistan also supposed your name for physics. Fortunately I know u (respected) from the beginning.. Thnx sir

[@shashibhushan5999]

This man is god of physics

[@jagatnarayan2515]

Awesome explanation

[@abhishektrivedi7590]

sir apka tution kha par h

[@manaschakraborty6593]

is there any change of refractive index if we sink a prism into water?please reply

[@manaschakraborty6593]

thank you sir

[@purnima_09]

Physic actually queen of all subject 💫💫💫😊
I realised becoz of u sir
Thnk u so much 💓

[@rashmiarora1981]

from ur which video can I do the very basis of optics sir?

[@shivanipanjwani5405]

what an explanation

[@parikshitchoudhary2179]

Sir apne ye rules ke upr diagram bnaya h who glt ha as bend toward normal hota or apne away from normal bnaya h tho sir ho ske tho confusion dur kre mera

[@ilyasorakzai7072]

YOU ARE THE BEST SIR I EVER SEE IN MY LIFE .I DONT KNOW WHAT TO SAY SIR LOVE YOU

[@anitashahdeo5344]

explanation 👏👏 hats of

[@KCJha123]

Thanks so much sir 🙏 👏

[@drabhishekparihar]

wonderful!!!

[@mrviveksharma2982]

Sir Aap 10th class ke video upload nhi karte hai

[@meermuzamil4514]

Sir your lecture is amazing mujai aapka sara lecture samaj aaya jo hamara teacher ha uskha samaj nahi aata hai mujai light sara samaj aaya jo aapani bola sir eak request hai aap lesson no. 2 lecture dijiyai

[@shahidshabir3487]

sir board is not visible to us please do something.

[@samiranbandyopadhyay1393]

Sir normal incidence me i=0 kyu hota hai? ?

[@jitendrashukla7485]

Because angle of incidence is measured from normal. And in case of a ray falling perpendicularly at the surface, the angle between normal and incident ray is zero

[@sushmitkatkale6380]

sir , In case of Snell's law , if rarer medium is air and denser medium is water , mu=1.33 , if i=0, then r=0 , ratio of sin(i) to sin(r) becomes infinite .but mu= 1.33???

[@priyasingh-fr9vg]

ni bro in case of refraction we take different different angle at which incident ray is refracted then constant value shoud be get

[@kumarguddu299]

Nice sir❤️

[@zoyanoor1026]

MashAllah😍

[@himanshufittVlogs]

Sir you are lord of physics thank you sir this lesson l don't understand but when l see your video now l am....

[@rajnarolia1651]

Very helpful video...

[@funinformationinterestingz9066]

sir what is the difference b\w denser and optically denser

[@vatanbhardwaj]

optically denser means speed of light reduces when enter from air.
dense is related to density.
eg. brick is denser than sponge.
glass is optically denser than water.
brick and glass can not be compared for light
