idk what i have done but did something that seemed logical to me plss correct me.
thanks

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.its incorrect😭
lmfao i recognised the teacher from the handwriting 😭
oh lol
it is not 3.4
but 3.3 xD
hahahaha
wait
so theenergy is higher than what is required, what is the issue with that?
why cant it absorb only 10.2 and goto 3.4? will have to think about this. what was the explanation given by the teacher?
Sir a similar explanation was given by our chem teacher, he said that an atom will not get exicited if the energy is higher or lower, it must be only -3.4 ev. He said that no excitation happens and all the energy is used to translate the atom
yes sir it'll be great if you could explain it to us after that since even I didnt quite understand
this makes sense sir
I think the reason is,photonic energy is quantised....we cant "cut" some part of the incident energy.
sure but the amount you absorb is quantised na
but again, i will have to read lol
from the absorption spectra example, i thought it could work but will have to read properly
wiat let us summon some pros @myst1cboomer @amethystninja any inputs on this?
From what I understand, in such a case, it's like it absorbs and goes to an unstable orbit and then releases a very specific amount of energy in the form of a photon to go to the just lower orbit
But that's when you assume it can do that
I think since the initial absorption leads it to an unstable orbit, it simply re-emits all the extra energy and returns to its original state
Nothing happens
It is a rule that the energy should be exactly same as the amount req for transition
but why? what explains it?
I think it is the fact that more than required energy makes it unstable in that state and therefore because of development of some potential energy kinetic energy decreases and velocity also decreases and nh/2pie rule gets broken?
The main thing always is the nh/2pie rule
Aarey sir 🙏🙏
who?
extra energy will convert into KE
bj
most probably
yeah
lmao
How was your experience with him?
accha padhate hai
ngl
yeah
just keep on following him
dpp puri krlena
vo to milti hi nhi💀
book hogi unki
wtv that was
sheet
i forgor
yeah
class notes are pretty good for revising
yeah his writing and notes are completely ironic
but bro extra energy to KE me convert ho jati hai
Sir, what he told later in some topic that the extra energy will convert up into KE so is this another exception?
i dont know about this :D
i think i should send you his explanation
please delete after watching it 😉
cool ty :)
yea mb but i excess energy first gets stored as potential then gets converted correction
angular momentum wala toh break hoga
sir i meant something like this:- say in some scenario, the energy of transition from some orbit to other is 3.5 ev (hypothetical value, just saying). and we got photons (EM radiation in the sense), of say 5 ev. now thinking of it like this, photon is the most fundamental level of energy packet, so if we think like the 5 ev photon (say 1st one in number) will dissociate into two of energy 3.5ev and 1.5ev, then it is not possible. hence the incident energy must be equal to the energy gap required to jump,not less,not more. because we cant "dissociate" this incoming photon acc. to our needs.
but excess energy gets converted to KE ig
Electronic transitions have a narrow linewidth i.e. a range of values just above and below the frequency where transition occurs. It does exist and transition does occur if the frequency falls in that range but it is so narrow that we can neglect it for jee purpose
So if you are solving any numerical and it’s not the exact value just mark transition won’t occur vala option lol
but that is due to uncertanity in energy in a present orbital stage right? ig we would ignore that at h.s. level.
Yeah
this thing is hell confusing
is this sorted? shall we mark this as solved?
not sorted ig but if you want you can,Sir
What do ya need? And please close your own posts :)
But won’t that energy gap somewhat act as a per day threshold energy? Cuz we can’t write the energy in form of h x frequency , and wkt KE = h[given frequency] - h[threshold frequncy] so here we aren’t considering that the electron doesn’t get excited if it is not the exact energy right, instead we r considering it should be more than minimum fixed value right?
Lol just keep in mind that exact value nahi ho toh no transition (there’s a linewidth as I said but negligible so ignore)
this @Gaurav
so even if thodi si bhi value upar neeche ho gyi to transition ni hoga?
