XII_86.Dual Nature, Photoelectric effect, Experiment.

[@araynakumari6660]

sir ap mind-blowing pdhate h...seriously I m a great fan of URS..itna clear concept..thank u sir

[@muskanmishra923]

Sir! You are the best physics teacher!! :)

[@rakibahmed3553]

muskan mishra wat u r saying

[@rakibahmed3553]

muskan mishra i wil teach u ok

[@rakibahmed3553]

muskan mishra free tution

[@harshitkamani8878]

awesome explanation very very useful

[@wahphysics6443]

sir why diffrent current is made at 0 v for diff frequency when intenssity remains same

[@rutujalohakare6250]

Sir may be its happen in photoelectric effect ki ek samay aisa bhi ayega ki material me se sare electrons khatam ho jayenge and it will decay. Then why it doesnt happen?

[@gameplay3dshahzad]

Sir Great job 👌

[@arindamgupta3416]

sir after the emission of electrons by photon, the metal becomes positive charge. so why will not that metal attract any negative charge ??

[@jatinmukhiya4061]

sir it means current still flow in the 0 volt or when the PD is 0 is it??

[@subodhdahiya3099]

Amazing sir ji

[@rahul12441]

Sir are really wanted to know is pradeep your own publication book ?

[@nazishqureshi5033]

sir is there lecture about frame of reference,inertial frame of reference ,non-inertial frame of refernce ,einstien theory of relativity and galelian transformationsthanks

[@alimustafasherwani9131]

Sir why stopping potential directly relate with frequency

[@niharshah079]

SIr what is meant by the rest mass of the particle denoted my m knot ?????

[@nisharani1512]

sir i wantd to ask u .... sir wen electrons r ejectd frm a metal..... if frequency f d light cuming is more thn wat is needed by a electron ... that is minimum work function....sir suppose it comes out n gts velocity 2m/s ... thn wil move wid 2m/s sir is this energy will becum 0 ever???

[@iffatnowshin1037]

Kin logone unlike kiya 😑😑. .Sir boht accha parhati he. ..

[@mehenaz01]

App asa nahi kah sakta Kyu ki kiska dimagh kasa hotaha toh eslia kiss samjh ataha aur kisa nahi

[@amalagarwal4589]

Sir how can I find plank constant if light of 3000nm & 4000nm respectively is incident on sodium cathode and for both stopping potentials are 1.85&0.82 respectively

[@yasirmd1185]

Really thank you.. It helps me more

[@nisharani1512]

n wen its velocity is going to be 0...?? will it ever stop.. or keeps on moving ?

[@rupamsingh6131]

sir ap kuch notes ni dete h kya.... I mean language

[@onlyDhiru.]

Awesome sir your teaching skills and experience is too good thank you sir

[@kavyar724]

sir the current always flows from negative plate to +ve plate inside the voltage source and from +ve plate to negative plate outside in the circuit.Then in this case how is the direction opposite??

[@siktayadav6811]

Why this hole is provided.?? Then how it can be Evacuated tube?

[@aliatif8209]

sir mjhe mechanic ka bare ma apka koi lecture nahi mil raha plz help me

[@NishaYadav-sc1gf]

Sir really thanks for this vidieo ...

[@kalpanaphysics]

Sir, why current increases first and then saturates for fixed intensity as we increase the anode positive potential.

[@aasmaansingh5675]

Didi

[@abhijitthorat9296]

sir whch cet book should i refer to crack the cet? 4 physics subject?

[@aniketthul]

sir,why k.E of electorns are diffrent.....you said that electrons inside the conductor spend their energy to come on surface....but in electrostatics we studied that all electrons are distributed on surface because of repulsion

[@TheHimaLaya-y8h]

On u tube u r the best teacher for physics ❤💜💓💗👍💟

[@architpanwar4784]

sir when we apply negative potential then you have said every electron is left with different energies and current becomes zero when we apply max negative potential but then electrons which do not have max energy then they should move in opposite direction .... but why they are not doing so???

[@Vikashsharma-zx8de]

+Pradeep Kshetrapal sir i had conflict of theory because einstein photoelectric effect demonstrated on x ray not visible light they why we are going through text books whivh are i hope totally wrong no light have power to emit electrons from metals.... i want your ideas about it...

[@rishipatel7147]

Remember whenever negative potential is increasing then velocity of electron is decreasing because of opposite force on it .its mean that the time is increasing and time is increasing then current is decreasing

[@AslamKhan-cz9my]

can you explain how current is more in green then yellow at zero potential plzzz

[@mtalhashahzad899]

sir is their any teacher of chemistry like you?

[@amantak4001]

All the electrons of same radation have different energy why?

[@VIVEK-ru4rg]

sir plz. help me in solving this question....when a metal is irradiated by monochromatic light kmax. =1.2ev .frequency is inc. 50% then kmax. =3.6 ev ..find workfunction..sir plz. help

[@8982601240]

why is there is 2 video of 1 topic?

[@kunibaki]

MEANS SIR ANODE PROVIDES POSITIVE ENERGY TO THE ELECTRONS HAVING POSITIVE ENERGY THEN HOW THEY CANCEL EACH OTHER PLSS SIR HELP ME IN CLEARING MY DOUBT THANKYOU SIR

[@ravleenkaur4455]

U R THE best teacher sir,ur explanations r really wonderful. I need no tuitions.

[@wahphysics6443]

why doesnt the current increase indefinetely with voltage

[@rizwanshaikh5275]

In video tell about whose board Maharashtra 'CBSE icse

[@kratitak3375]

Sir in this emitter or collector which one anode and cathode:-)

[@muskanmishra923]

Krati Tak emitter plate = cathode collector plate = anode(+ve)

[@Bharat95Gadhavi]

no it depends on cell...here emmiter is anode ...collecter cathode....positive negative depends on p.d we apply

[@nabiagulistan1291]

Excellent lecture by excellent teacher.

[@maahi1768]

Why kinetic energy is eV

[@kratitak3375]

In this emitter or collector which one is anode:-)

[@PhysicsAvi]

Collector

[@amalagarwal4589]

Sir please help me to solve this numerical If 5% energy of a monochromatic light source is converted into light of wavelength 5000nm.if the power of source is 100 they how many photon of light will be emmited by it per sec.

[@amalagarwal4589]

Thank u sir

[@mohammadayubbugti8918]

Sir you are too good keep it up sir

[@gauravraj4441]

sir ...you are adorable...!!😊...this is the first video of yours which I have seen..n...for this I m very glad to you...now on wards i shall be watching your videos only for physics...!!! thank you sir..😊

[@samarsingh9608]

realy good, Thankyou so much.

[@muzammilkalhoro4909]

Every time sir u are breaking your own record in teaching🖤🖤🖤respect

[@abhijitthorat9296]

sir its k........ my exam is in feb... thanx sir 4 consdring my commnt.. and 4 uploding such nice videos... it helps us alot......

[@cuckoo242]

extremely helpful....thanku sir...God bless u..:)

[@Bharat95Gadhavi]

it is not in all case that anode negative and cathode is positive it changes on type of cell...

[@atishupadhyay6696]

Bharat Gadhavi 👏🏻

[@dr.j.k.upadhyay3068]

U r right sir work function is same for all e of a metal

[@amanmalhotra724]

sir there is a numerical a biconvex thick lens is constructed with glass. each of surface has a rad of 10 cm and the thickness of the middle is 5cm. locate the image of an obj placed far away from the lens [meu for glass is 1.5] ans is 9.1cm from the farther surface on the other side of the lens.

[@rajendersingh2319]

So nice sir...

[@shriramgupta988]

Thanks sir . Very nice explaination.

[@tribhuvankushwaha6397]

SAB PADHE SAB BADHE

[@UshaDevi-ps7vn]

Sir physics ki kuch video choti bnao or kuch hindi m

[@prathvirajvernekar5737]

Good explanation sir

[@maheshlamuchhane4285]

best teacher

[@prabhunantha3080]

Very interesting sir

[@raghavrajdevkule7252]

SIR I FIND UR LECTURE MORE INTRESTING ,AND IT HELPS ME A LOT AS I M NOT GOING TO ANY CLASSES...I M TENSED ABOUT THE BARD EXAM PLZ.HELP...

[@dr.j.k.upadhyay3068]

I think work functions is different so wny k e is different

[@dr.j.k.upadhyay3068]

You r right sir work function is same for all e of a metal

[@arjyabasu1311]

Thanks a lot sir!

[@shabbirshabbir3640]

the vedio is full of disturbance that's y I was unable to listen properly so plz look after that when making another vedio

[@salonikumari4208]

Thank-you so much sir

[@kunibaki]

sir thankyou so much for clearing my doubt

[@rohitrohan6512]

👍👍👍👍

thanks sir

[@divyanshubajpaibajpai4637]

Ok thanks

[@pratikkumar6066]

my goodness

[@opticsanand]

Say in english sir.... Pls

[@vikramgandhi8382]

bahut complicated kar diya sir aapne

[@kratitak3375]

Sir in this emitter or collector which one anode and cathode:-)

[@kratitak3375]

In this emitter or collector which one is anode:-)

[@amantak4001]

All the electrons of same radation have different energy why?

[@salonikumari4208]

Thank-you so much sir
