Ohhhh gooddddd your lectures are soooo helpful you summarise different concepts of one topic in each video and it's sooooooo time saving!!! Thank you so much ❤
The energy of the incident photons would double, but the photoelectron must escape the material it’s bound to first. It requires the threshold energy of the material just to be free with kinetic energy zero. So, no it wouldn’t double. For example : let’s say a metal has a threshold energy of 1eV. A photon of 3eV hits it. An electron might get this energy and free itself and have 2eV left over as kinetic energy. Now if that incident photon had twice the frequency it would be a 6eV photon (twice the energy.) The electron would pay off the energy holding it (still 1eV) and have 5eV left over as kinetic energy. As you can see, it will have more than double the kinetic energy it’s less energetic partner had.
Sir apna ya kaha ha ka photon massless ha to phr relative mass b zero hona chahia....... but apna kaha ha ka infinity ..........or v=c ........ phr to zero hi hona chahia kuka nicha b zero upper b zero .......google pa zero a raha ha....... kindly guide mee....... confused ho gy ho😭
How photo electric current is independent of frequency bcz in definition there is a word of suitable frequency if frequency will not match then current Will not eject
Assalam o Alaikum, sir. The slope of stopping potential ( V°) and frequency ( f ) gives the constant, "h/e" - does it have any particular name, if yes, what? kindly let me know, thank you.
Sir in case we use metal of greater work function then Jo graph h us mein threshold frequency vhi rhy GI aur energy decrease ho jai GI ......graph will tilt toward x axis....kindly reply
Eik jagah eik graph ma8n I current hai eik main intensity uppar walay graph main intensity pay independent thi ab depentdent hai bohat confising lecture hai

Great lecture but kuch smjh nh aya awaz ki waja se ..ghonj thi awaz me😢😢46 mnts p 2 hours lag gye .. 😢
Helpful! Thank you for serving humanity:)
The thing that I'm watching this lecture on 11th November 2022
😭😭😭😭 I wish I had found you earlier 😔😔
My legend sir
Please upload next part of this chapter 😋
please
Bht aala
Sir bohat acha tha lecture
MashaAllah....i m big fan of your sir
Your writing is very gud sir

thanks sir amazing concepts but sir plz Is chptr ki video dobara upload kr dijiyay ga Thora shor ha .... Jazak Allah...
Sir for photoelectric effect energy of photon0.5MeV ya us se kam ho gi ya 0.1 se
Thank you so much sir you solved my biggest problem due to this lecture 👍👍👍

Please sir MDCAT na socho kuch ECAT walo k Lia be lecture banee sir ?
Thank you so much sir.
We are highly thankful to you.
Amazing ❤❤

Sir i am your new subscriber.sir background myn thori disturbance hai.jis ki wja se awaaz itni clear nhe hai.
But your lecture is very helpful sir.
sir plzzzz can u make this chapter lectures again for us . its too difficult for us bcz sound is not clear .....we need this plzzzz
Same problem time bohat zaida waste ho rha

Sir kaya pair production occur dosere rays show karsak tey ha?🤔
Jazak Allah
Sir is video min shor boht hai, boht Kuch samajh hi nhi aaya, wese Baqi sab ok hai, thx sir
Amazing ❤🎉
SIR PLEASE IMPROVE SOUND QUALITY ALL THE STUDENTS ARE REQUESTING THIS.
Try using Bluetooth or headphones it helps so much

Q: Agar frequency threshold frequency sy kam ho or double kary to K.E pr kaisy effect karyga

Is may V2 ki frequency zyada hai q k ye 0 k qareeb hai ?
AsslamuAlikum Sir.Sir please upload lectures of compton and pair production too kindly Sir will be very thankful of you.
Sir app main 2nd year chapters ky formulas open nhi ho rhye hai. Ap ny in chapters ky formulas upload kiya hai????
Does fo=workfunction

Maza a gaya
Sir plz black body radiation prhaie oske boht sawal arahe h test main
Sir plz upload other chapters too.
Sir why its graph K.E vs F is straight even u re saying that k.E depeds upon frequncy but not linearly bcz work function Ka bhi to frequncy minus hga
Same question 😢
Boht shor hai background mai.. otherwise 👌
Sir next half chp???

Sir aapnay vid mai kaha k radiowaves k ilawa sari rads pair prod karsakti hain?
Sir pair prod to sirf gamma say nahi hota?
That's for photoelectric current or as a whole for interaction of matter with radiation
Thnx sir
