Sir g electron 4.9 volts par hi q apni apni energy loose krta ha. Is ka pecha Ka reason btain. Or us waqt inelastic collision hi q hota ha?????

[@Eduphile]

Kyunki discrete amount ma hi energy absorb ya emit Kar Sakta h isliye. Aur jyada jaanna chahte h toh spectroscopy playlist ma absorption and emission spectrum wala video dekhe

[@sushma8080]

@@Eduphile but you said discrete means 1,2,3,4..... not 1.2, 2.3, 3.3 or 4.9 etc so in this case you are saying 4.9v is discrete. how?

[@Eduphile]

@@sushma8080 dekhiye aap Sahi bol rahe h , humne toh bus ek example Diya tha , discrete Ka matlab aisi values jinki beech ma koi value na ho

[@heheyoitsme1590]

@@sushma8080 Discrete in the sense..... an integral multiple of 4.9 (here if you notice in the graph the current drops at 4.9 and then again at 4.9 x 2 = 9.8 so current can drop only at integral multiple of 4.9 that is 4.9, 9. 8, 14.4,19.2 etc and not like 1.2 X 4.9 or 2.3 X 4.9) an electron can stay in integral values of fixed energy levels( which is 4.9 in this case)

Sir aapne kaha ki electron jb excited state me jata h to or enery absorb nhi krta, esa kyu?
Ek or chij yadi e- 1st excited state se 2nd excited state me pahuchana hai to enery to deni paregi or jbtk o enery absorb nhi krega tbtk 2nd excited state me pahuchega hi nhi, lekin esa to hota nhi. Please explain i am confusing

Why current dropped to zero..... We are increasing voltage.... So how it could possible

[@NayaNepalYt]

Election attained the higher energy level so they are stable at that moment. When they were stable then atom stops to emit electron. So current fall down...

[@gamesden8021]

Sir aik reason bathain kay elastic collision ma tu electron ki direction change hoti hai tu woh anode tak kiasy jata hai plz sir reply karhain

[@ijazmuhammadijaz8905]

8:47 sir g whole atom will go to exited state or only electron of this atom ?

[@Eduphile]

Electron in the atom , so we can say atom

[@ThesurajSuraj]

[@Eduphile]

[@sapnajangra878]

Why current drops only at multiples of 4.9

[@Eduphile]

Franck and Hertz noted in their first paper that the 4.9 eV characteristic energy of their experiment corresponded well to one of the wavelengths of light emitted by mercury atoms in gas discharges. They were using a quantum relationship between the energy of excitation and the corresponding wavelength of light, which they broadly attributed to Johannes Stark and to Arnold Sommerfeld; it predicts that 4.9 eV corresponds to light with a 254 nm wavelength.[2] The same relationship was also incorporated in Einstein's 1905 photon theory of the photoelectric effect.[12]

Mai aapko easy language ma samjhata ho
Jaise atom ko Humne energy diya woh energy gain karke excited state ma aaega phir collision k baad energy lose kar dega jitna usne gain kiya tha ( same amount ) . Isse ye pata chalta h ki atom k discrete level ma energy hoti h

Do the all tree peaks in graph belong to first excited state or first,second,third excited state respectively?? Please answer with explaination!

[@Eduphile]

In all excited states

[@sushovansarkar5822]

All the peaks is corresponding to 1st excited state, not other higher state. Because the difference between two successive peaks is 4.9ev(i.e, 9.8-4.9=4.9,,, 14.7-9.8=4.9) which is the value of 1st excited state of Hg. The concept is that if at 4.9ev , one atom of Hg is excited in 1st excited state , then at 9.8ev , two atom of Hg is excited in 1st excited state (4.9+4.9=9.8) ( not one atom in 2nd Or higher energy state) and so on.
