[@kgnstarinterior2118]

sir you have proper words to explain the the particular topic of physics but we have no words to explain your high skills of teaching

[@physicistkafeelchanna3519]

dear i need a indian books of physics from grade ninth to 2nd year plz tell the names of good books

[@arindamgupta3416]

I am a 1st year btech student... i have been watching your videos since class 11. still now i watch your video to clear many concepts. In my life I have never seen as good teacher as you are. you are my God sir. future kids need you

[@anish895]

Really bro

[@ijazahmadconstructioncompa7860]

God is Allah.

[@yashsharma3169]

Behtareen teacher of earth , kaafi jyaad acche se samjhaaaya gaya , sir aapke jaisa teacher kahi aur nhi dekha

[@mehmoodkakar5767]

No doubt. Sir you have a good knowldge and goid explainer as well

[@ManishKumar-jc2su]

Sir is there any redistribution of energy in differaction also?

[@muhammadishtiaq4331]

Wawo sir ....iam also lecturer of physics but i didnt came acrosss such a lagend teacher

[@alphabetagamamotivationhar4513]

ur explanation is so much easy.

[@Zahra-bi4bw]

I wish you were our teacher in college 😢

[@iramkhan1045]

Veryrrrrrrrrrrrrrrryyyyyyyyyyyyyy good explanation thankyou soooooooooooooo much sir

[@AkashKumar-ve7ow]

Concept chamak gaya sir 💯☺️

[@sudarshana7344]

Sir your explaintion,ur examples ,help me a lot to understand concepts nd your drawing is vry nice

[@AnubhavSingh-vv8gn]

Where to get the complete 11 12th lectures of Pradeep sir..

[@bharatkumartajwani3951]

Sir there is no topic of michelson interferrometer????/

[@nitinchoudhary5507]

Sir why there is shadow as the secondary waves are produced at the aperture of the obstacle in 1st example which you have taken at starting. The waves produced by the secondary source at the aperture will flow the waves in the front direction and the screen will be bright.So why there is appearance of shadow means dark area on the screen Sir?

[@Zahra-bi4bw]

Sir you are great teacher.

[@khansirmotivational9050]

Thanks sir bahut achha se padhate h such me

[@fakhr-e-farooque7353]

Sir u r superb thanks allot . I am from Pakistan and I watch your lecture since 1 year . Much much love from Pakistan .

[@yashmeena8686]

Why their is not superposition b/w 1 and 100 point

[@rupeshhirve4939]

Thank you Sir, your lectures are more helpful.

[@upscfansclub4736]

Sir aapke jesa youtube par koi nhi padh sakta hai i miss you sir 😞😞😞

[@easyphysicstutorial3613]

Now you r the greatest teacher of physics

[@amartyamondal3984]

why matter act as an obstruction to EM Waves i.e. how matter behaves with EM Waves? what causes the wavelength alteration on the interface of different media? when light gets refracted and when will it get reflected? - please sir answer these questions thanking you in anticipation.

[@sukhwindersaini1523]

may God bless you with a long and healthy life sir..so that you can cherish your legacy!! Thank you so much

[@Sanaya_Pathak]

but why it diffract anly if wavelength of light is comparable to dimension of obstacle??

[@lathapurushotham6345]

How can we say no of sources required for diffraction is many you had split the sources for explaining destructive superposition so explain

[@archanaadarsh4273]

The best explanation. I mean sir made it do simple🤗

[@Sanaya_Pathak]

though medium of propagation is same why light diffract?

[@missnycvideofarooqui243]

Awesome sir!!

[@kgnstarinterior2118]

sir if sound has larger wavelength than light then why light travel faster than sound because use to raste mien ane wali chizo ki wajah se sound ke mukable kum speed se travel karna chahiye or sound ke pas larger wavelength hoti hai to woh to easily or faster travel kar sakta hai please reply as soon as possible pleassssssssssssssssssssssssssssssssssseeeeeeeeeeeeeeeeeeeeeeeeeee

[@shivamtomar7229]

sir lecture was very good,upload the lecture on polarization fast sir.

[@rishabhdhiman6567]

sir I have one question . sir is your lectures and hc verma is enough for iit jee

[@anjalisindhal8633]

Rishabh Dhiman yes bro it is surely.... Sir's videos help build the conceptual knowledge which is important aspect in preparation of iitjee

[@IMRANKHAN-oc2jo]

superb lecture thank you sir.

[@mmashrurhussain1042]

+Pradeep Kshetrapal Sir, I have a question.. why sometimes we see lens is used between slit and screen to observe diffraction in case of fraunhofer type? Is this the reason for getting clear view of dark and bright fringes or to differentiate that?

[@mmashrurhussain1042]

+Pradeep Kshetrapal thanks a lot

[@gauravtiwary4665]

[@gauravtiwary4665]

[@poonamduhan3326]

thank u so much sir. . u explain every concept in such a way that it becomes very easy for every student after seeing ur lectures. u r doing a great job. keep going.

[@sunmoniborah6589]

SIR YOU ARE THE BEST TEACHER IN WORLD.............I LOVE YOUR TEACHING METHODE,,,,,,,,,,,,AND I ALSO LOVE BEAUSE YOU DONOT FOLLOW NCERT BOOK,,,,,,,,,,,,,,,,,,,

[@Doctorsings]

spacial coherence and temporal coherence difference????

[@Doctorsings]

sir what is fermet principle????

[@viveksaraswat4564]

Sir same medium m hote hue bhi light apne path se deviate hokr shadow reason m kyu enter kr jati h ???? Plz reply. Agr koi mera comment pde or use iss question k answer pta ho to plz reply krna .

[@khellagpreet2460]

Due to diffraction(property of bending of light)

[@mushahidrazaa5150]

sir,can you upload numbrical question abuut impulse?

[@lathapurushotham6345]

is intensity inversely proportional to h distance between two fringes

[@muhammadishtiaq4331]

No

[@yashicbse5677]

No

[@hrithikroshan4883]

Rest in peace Sirji 😢😢

[@vidhyarthisunav]

sir we saw that more the wavelength more the diffraction hence more the scattering but in class 10 we also saw that sunset appears red because high frequency waves are scattered in their way reaching earth but only red colour stands...though scattering is more for red colour yet it reaches us...isn't it a contradiction... plz help..!

[@amartyamondal3984]

+Sunav Kumar Vidhyarthi You have a misconception, according to Rayleigh Scattering of light, the extent of diffraction is inversely proportional to (wavelength)^4 red light being larger in wavelength scatters least but during sunset as because light has to travel more distance even res light gets scattered but by small amount,for that reason the intensity of light reaching us is reduced that is why the sun looks dim and sky also looks slightly orange.

Superior polarization retention through engineered domain... ///Nd.D

[@sarfarazkhan-ey1ho]

sir are you alive

[@nawazofficial5934]

Sir pls what your qualifications📖

[@vinayjangra1401]

bhai tn bhut chhoti baat kardi. jaisa vo padhate ha qualif. ki aukkat hi nahi

[@bb.....3843]

Baat to shi hai

[@gurz5868]

sir , you are great

[@sunidhidwivedi2181]

sir why have u written asin theta to be equal to lambda instead a should be equal to lambda because you have considered AB =a. at 36:50??

[@sidhantsashwat3893]

bt sir blue has longest wavelength...to vo zyda deviate kregi

[@muhammadishtiaq4331]

Red has logest wave length dear

[@spssaikia]

lecture was superb!!! Please upload Polarisation.

[@inclinedscorpio]

sir you told in this lecture(40:14) that path difference is 1lambda but interference is held by only those having path difference 1\2lambda ,sir how is this practically possible as the 2waves from the end(having path difference 1 lambda) are meeting at the same point so there 1constructive interference should also form!!!!!!

[@inclinedscorpio]

+Pradeep Kshetrapal thank you sir ! I got it!!

[@chikhalabastii.avinash5125]

thank you

[@lathapurushotham6345]

how to calculate width of central bright for interference

[@healthydiet37]

sir if a light bends always towards shadow area then why our shadow become very large at morning and evening time ;and our shadow is always less than our actual height but different time our shadow is greater than our height why please reply

[@healthydiet37]

please reply

[@THEPIRATEsg]

Yes it's true that light bend towards shadow and this doesn't mean that that shadow will always be smaller than the object. Your shadow is larger than you during evening is because of the angle between the horizon and the source and due to diffraction your shadow is just getting little bit smaller around the edges compared to what geometrically should be if light is considered as a ray. Hope this helps.

[@shriramgupta988]

Thanks sir
