Very humble dialect... Sir is teaching in a easier way.. Thanks Sir I am a student of this standard... I respect you sir.. like my honourable teachers. I am from Pakistan..
Dear Pradeep, I am a Pakistani Engineer. Though I have no concern but l listen to ur lectures on Physics for pleasure and knowledge whenever I am free. Ur concept clearance and grip on physics and the the way u explain to the audience, makes u perfect and impressive. It indicates that u r an industrious professor.May u live long and serve to teach.
Sir ji aap 21:02 >> bataya har electrons ke pass same energy hoga ...but why..??? Jo andar se nikle ga o electrons , bahar se nikle ga o electrons ke pass energy same Nehi hote. But u say har electrons ke pass energy same hai.. Plz help me....koi e ans de sakta he plz help me I confuse
sirji at 25:50 when youare discussing different frequenices (current vs voltage) sir aapne aha tha shuru ka current thoda zyada hoga sir but why? agar frequency change karne se no of electrons ejected does not vary
nimish bansal as electric current is time rate of flow of charges through any cross section... since increase In frequency cause increse In kinetic energy of election... hence rate of flow of electron increase... this cause increase In current there....
Ye theek hai ke frequency barhane se sirf energy zayada hogi aur number of electrons same rahain ge, laikin zara graph par ghor karo, jab potential negative hai, to sirf wo electrons do sirface ke qareeb hain wohi bahar aa kar ciruit mein jayenge kyunke baqi electrons ko negative potential rok le ga, jab potential zero ho ga electrons ko koi rukawat nahi hogi aur sab electrons nikal kar fow kararin ge aur current maximum ho jayenga, ab agar current ko aur zayada krain to current mein faraq nahi parray ga kyunke positive potentoal electrons ko bahar nahi nikal sakta balke sirf bahar nikle huay electrons ko tez kar sakta hain jabke negative potential nikle huay electrons ko rok sakta hai
sir in the previous lecture you have given an example and told that no of electrons ejected depend on frequency and not wavelength, that is wrong right?
Sir you are teaching style, methodology , words u choice are very easy and fruitful... actually I am from Pakistan and presently physics teacher at school level I followe you regularly when I face any difficulty then I search your leactures .... amazing sir
thank u sir this video help's me a lot .. i am afraid of this chapter ... at last before 3 days my xam i go through this video .. and i think .. this modern phy izz too interesting ... hat's off to u sir .. u solved to many problems of students .. i am glad to have a mentor like u ...after watching ur videos .. i realized that ... physics is awesome subject .. .. once again thank u soooooo much sir .. :)
Hi sir, I really loved the lecture, was a lot helpful.Sir, I am still having one doubt. Your assistance will be a lot appreciated. The intensity of light falling on a plate is given by power per unit area or Energy per unit time per unit area. Energy will depend upon the number of photons as well as their individual energy. So if I use 3 different bulbs of same power but different frequency v3>v2>v1 then the number of photons of each wavelength has to be different to keep the power constant, n3
Sir par abhi bhi hsc ki textbook mein INTENSITY directly proportionate to AMPLITUDE diya hai kya vo galat hai...? Anyone plzz help me out if you know the answer
Higher the kinetic energy of electron, higher will be its velocity and higher the current, isn't it sir? So how is saturation current same for various frequencies of light hitting the metal? I mean though maximum no of ejected electrons is same, they have various velocities. Really confused 😑
Saturation current is attained when all the possible electrons that was emitted from metal reaches the plate. It depends on intensity of source (and thus on no. of electrons removed per second) but independent of velocity. I am a student so do verify it!
after watching your videos physics seems to be a intresting subjct, youe videos helped me a lot sir i recomend all those cbse students who are preparing for boards examination, you can get a home tutor 24×7. Thank you sir 😃

I started loving physics after watching your videos
This video helped me a lot! THANKS, Love from Pakistan. 😊😊
Me too didu

really helped me a lot i suggest every student to see these videos it helps

Sir is no more
Sir ji aap 21:02 >> bataya har electrons ke pass same energy hoga ...but why..???
Jo andar se nikle ga o electrons , bahar se nikle ga o electrons ke pass energy same Nehi hote.
But u say har electrons ke pass energy same hai..
Plz help me....koi e ans de sakta he plz help me
I confuse
sirji at 25:50 when youare discussing different frequenices (current vs voltage) sir aapne aha tha shuru ka current thoda zyada hoga sir but why? agar frequency change karne se no of electrons ejected does not vary
bcz depend upon on the intensity of light
nimish bansal as electric current is time rate of flow of charges through any cross section... since increase In frequency cause increse In kinetic energy of election... hence rate of flow of electron increase... this cause increase In current there....
thanx alot sir

sir, thank you very much for discussing this topic so easily ....
Sir intensity badhane se photons kaise increase hote hai? matlab aisa Kya ho rha hai usme jo increase ho rha h?
Thanks a lot sir. These videos helps me a lot . I am preparing for board exams with the help of these videos.
+shivani choudhar I am also doing this, If you have any confusion tell me. Thanks
Sir is work function is equal to eVo where Vo is stopping potential?
Awesome video
Sir you are teaching style, methodology , words u choice are very easy and fruitful... actually I am from Pakistan and presently physics teacher at school level I followe you regularly when I face any difficulty then I search your leactures .... amazing sir
U r the best teacher of universe
great lecture.
seen almost all the video lectures from different sources but this is best.Thanks Mr.Pradip Sir
thank u sir for making each chapter easy
sir would you tell me about the potential of plate emitter
Sir,Is work function W=eVo ??
thank u sir this video help's me a lot .. i am afraid of this chapter ... at last before 3 days my xam i go through this video .. and i think .. this modern phy izz too interesting ... hat's off to u sir .. u solved to many problems of students .. i am glad to have a mentor like u ...after watching ur videos .. i realized that ... physics is awesome subject .. .. once again thank u soooooo much sir .. :)
same feeling for me to!!
Sir it's really great for me , so thankz Sir, I love physics very much
Sir on increasing intensity stopping voltage remain same but on increasing frequency stopping potential remain same why?
Sir very good explained..... Sir kindly name the book from where your are guiding us
Thank you so much sir...
Your teaching style = awesome
ye pura chapter he kya ya half he...???
can we get photoemission with an intense beam of radio waves?

Anyone plzz help me out if you know the answer
Pradeep Kshetrapal thanks sir :)
great sir
you are the great incarnation of deity
Sir your way of explanation is too good

Really it's helpful
M preparing for board exam.....from ur videos.....tysm.....Sr
V v easy explanation
Sir Why Current Is Constant After some Time Increase In P.D.? ANSWER Please Sir
Coz ...all electrons are attracted by (+ve) volt.....
At first this not happen
Sir superb lecture I understood the photoelectric effect
sir you r good teacher as teacher wants
sir you are genius......i m literally fan of yours
I can't pay for your job anything became less in front of their job salute sir
sir, compton effect ka lecture please upload karien.
love from Pakistan
dear teacher.!
You arepakitani
excellent sir!!
fabulous
Easy and understanding
great
great sir pardeep chacha

excellent sir
great explaintion
Sir Compton effect ka bhe lecture upload Karo na
tysm sir
Thanks
Thank u sir
Sir tusi great
sir that's Tooooooo good thank you SIR
Thanks
Nice
Sir you are great teacher in social networking site but content is unsufficient means numerical nahi hai. So concept is not So clear...
I am so handsome that I don't need to study....
