Ionization energy can be of two types in metals... metals can have low and high ionization energy. Now, the metals having low ionization energy is those in the first and the second grp. Because of the large size they can get off with their e- easily. Work function and threshold frequency are the same because :- it is the minimum frequency to eject electron from the metal. So, ionization energy is a whole diff. Thing here
Work function and ioinization energy are same ...work function is used in physics and ionization ener. Is used in chemistry. Now come on threshold frequency - this is mini.

Are bht easy hai Bhai smjao ki metal ke pass hai electrons aur ham chahte hai ki electrons ko hatyy toh hamm uspe photo's yabi light or radiation uspe chodenge aur metal ko electrons mie ionisation energy rehti hai for eg smjo 20 frequency chahiye electron ko nikal ne k liye toh ham Kay krenge ki light ya koi b radiation 20 frequency se zyada matlab 25,50,60 frequency Wale radiation us metal pe chodenge toh voo radiation k photos vo metal k electron pe laat maar k nikal denge aur thodi si energy niklege ise kinetic energy bolte hai toh k.e = hv-hv⁰ hoga
Electromagnetic radiation of wavelength 242nm is just sufficient to ionise sodium atom .then the ionisation energy of sodium in KJ mol^-1 is.SIR PLS ANSWER💯💯
27:48 isme sir ne minimum energy likhe h jbki vo minimum frequeny req to eject an electron called threshold frequeny No offense sir ne likhe energy h bas baki bole frequency hi h
Threshold frequency to lowest amount or frequency needed hota h electron nikalne ko or frequency of radiation matlab jitni frequency provide kri ja rhi h....frequency of radiation hamesha threshold frequency se zyada rahega
@@pranavbhati3350 frequency of radiation, threshold frequency se more, equal or less kuch bhe ho sakta h. Agar frequency of radiation, threshold frequency se kum h so photoelectric effect nhi hoga Agar radiation frequency threshold frequency k equal h toh photoelectric effect hoga par KE=0 hoga But frequency of radiation threshold frequency se jayada h toh photoelectric effect bhe hoga and electron k pass kinetic energy bhe hogi. Let's try to understand with the example A student need 30 marks out of 100 marks to pass in a exam. Case 1 If student secure less then 30 marks, student is considered as failed Case 2 If student secure only 30 marks, student is considered as just pass Case 3 If student score more than 30 marks, student consider as pass and bright student. Now try to correlate this 30 marks is threshold frequency because at which student is considered as pass student. And whatever marks obtained by student is considered as frequency of incident radiation. Now I hope you understand the concept. Thank you
frequency of radiation means- for what value did electron is emitting the radiation & threshould frequency means- the minimum frequency of the electron of the any substance from which the electron got deaatched from the substance....

The red glow of tail lights indicating another long drive home from work after an even longer 24-hour shift at the hospital. The shift hadn’t been horrible but the constant stream of patients entering the ER meant there was no downtime. She had some of the “regulars” in tonight with new ailments they were sure were going to kill them. It’s amazing what a couple of Tylenol and a physical exam from the doctor did to eliminate their pain, nausea, headache, or whatever other mild symptoms they had. Sometimes she wondered if all they really needed was some interaction with others and a bit of the individual attention they received from the nurses

Sir, I have a question about quantum theory, which of these quantum theory is most considerable?
Most probably Einstein's theory
Kyu ki Hertz k according electron tb emit hoga jb uski freq match hogi tb tk wo energy absorb karta rhega
Like: agr uski v° 50 hz h to tum 10 hz ki dalo to wo absorb krti rhegi jb tk 50 tk na pahuch jaye which will take sometime gap
Pr reality m wo koi time gap nhi leta photon dlte hi electron emit kr jata h agr threshold freq jitni h jo einstein n plank ki theory ki help s prove juya tha
Ki energy packet photon ki form m travel krta h naki wave ki ki absorb krte rho to packet girega or ee emit

@@pranavbhati3350 frequency of radiation, threshold frequency se more, equal or less kuch bhe ho sakta h.

Agar radiation frequency threshold frequency k equal h toh photoelectric effect hoga par KE=0 hoga
But frequency of radiation threshold frequency se jayada h toh photoelectric effect bhe hoga and electron k pass kinetic energy bhe hogi.
Let's try to understand with the example
A student need 30 marks out of 100 marks to pass in a exam.
Case 1
If student secure less then 30 marks, student is considered as failed
Case 2
If student secure only 30 marks, student is considered as just pass
Case 3
If student score more than 30 marks, student consider as pass and bright student.
Now try to correlate this
30 marks is threshold frequency because at which student is considered as pass student.
And whatever marks obtained by student is considered as frequency of incident radiation.
Now I hope you understand the concept.

The red glow of tail lights indicating another long drive home from work after an even longer 24-hour shift at the hospital. The shift hadn’t been horrible but the constant stream of patients entering the ER meant there was no downtime. She had some of the “regulars” in tonight with new ailments they were sure were going to kill them. It’s amazing what a couple of Tylenol and a physical exam from the doctor did to eliminate their pain, nausea, headache, or whatever other mild symptoms they had. Sometimes she wondered if all they really needed was some interaction with others and a bit of the individual attention they received from the nurses
Amazing session sir ❤ bench pe ldki baithi hui nhi nhi change bench pe ek ladka baitha hua .. 😂 best part sir
Hi jahnavi

Sir, does it mean that Work function = threshold frequency?? As both mean the min. energy to eject electrons ...
Nahi , sir ne galti se threshold function ki definition batate samay min. Energy likh diye hai agar dhyaan se sunoge to pehle sir ne min. Frequency kaha hai

U r great sir thanku so much for teaching us 🙏
Sir doubts don't come becoz the way u teach is amazing and every concept is very clear.... 👍
Sir I'm from Delhi but me momos nhi khati ☺️ and ab ap mujhe noval prize dijiye
Sir mai aap se hi padh kar apna half yearly diya aur bahut aacha gaya👍👍 sir numerical kar ne me problem aa rahi aur theory me koi doubt nahi rahta aap itna accha padh hate hai🤗🤗💕💕🔥🔥🔥thanks 🙏🙏 sir for making outstanding lecture s
Love from utter pradesh
32:02 kuch nhi aya😅😂
21:50 sir mai delhi mai badarpur ka hu lekin mujhe momos bilkul nhi pasand......mai to mahino mai kuch bhaar ka khata hu lekin wo momos nhi hota h 😅 .......

Sir AAPNE KAHA HAI KI WORK FUNCTION HOTA HAI MINIMUM ENERGY REQUIRE TO EJECT ELECTRON BUT AAPNE
THRESHOLD FREQUENCY KI BHI YEH HI DEFINITION BOLI HAI
PLZ...... iske baare mein thoda saa aur bta doo
work function = minimum amount of energy required to eject electron
threshold frequency = frequency corresponding to min energy required to eject electron & KE = 0

21:49 yes sir mai bhi Delhi ka hoon aur mujje bhi momos kafi pasand hai but mere sharir ko nahi 😢😅😅
Isliye mai momos nahi khata sir ab do mujje prize 😁
You had said that cosmic rays have the highest energy.
Actually gamma rays have the highest energy.
But you have explained very well.
Mainu pyarr ho gya jii. ❤❤
Bro cosmic rays have the highest energy
cosmic has highest..
Bahut acha padhate h aap sir... Mai dsssb tgt natural science k liye ye padh rhi hu.. Thank u so much 🙏
Sir I am from UK and the way delhi students are fan of momos my side also same condition and your all lectures are superb 👍💟
Same
Mujhe laga , United Kingdom ki ho 😅, to hindi video kyu dekh rahi ho.
Uttrakhand rocks!
Im from UK 11 💖

Sir Jaisa ki hum jaante hain ki ek photon ka mass zero hota hai, to phir wo ek electron ko displace kaise kar paa raha hai? itni to energy nahi hoti hogi ek photon ya photons mein ki wo ek electron ko hi displace kar dein, aapka ispe kya kehna hai???
Sir is bru coffe good or bad in taste
20:06 justice for boys 😂😅
1 more that what is the difference between orbit and orbitals
Orbits means shells and orbitals is present in subshells..
Last moment of 2024 🥺💓 only 45 minutes left 😄
21:29 momos khate khate padh rha tha 😂😂😂
#*Sir mujhe aapke 11-12 batch ka subscription chahiye kaise lu sir please reply*# you are very very good teacher....

Sir please upload phy video, mid sept me half yearly hai usme phy ke 7 ch aa rahe hai🥹
20:10 hum toh ladke h hmare saath toh aisa hi hota h🙃
btw mumbai m momos ka itna bhi craze nhi h😅
Kon kon 2024 mai aye ho topic dekhne😆
21:52 ham to bahar se hain par fir bhi khate hain 😂😂😂😂😂😂
Ashu sir : Hacker hain bhai hacker😂❤
31:23 sir there is a mistake - if threshold frequency is equal to the frequency we had given then photoelectric effect will occur with 0 kinetic energy but u said opposite
Thanks man, saved me from failing a test today
Sir agr hum photoelectric effect mn energy vo fixed 90 example ho or v jo ho wo 40 ho pr agr continously photon us p phre 40 frequency k to wo milake electron eject hoskte hn kya?
Sir I'm also totally dependent on you
Plank's constant is really awesome, It saved the world. A Stranger things fan can relate in the final episode of season 3
