a doubt

why is bohr orbit non radiating ?

even in this case shudnt there be em radiation

well... dats d basic assumption of bohr's model... he assumes the orbit's to be consisting of stable energy level... though practically an electron radiates energy, it is assumed to be consisting of constant energy as long as it is in a particular orbit...

this assumption is same as, v consider earth as a stable object for all practical purposes in daily lyf...

hope ur doubt is cleared... [1]

yes gagar i know that exp , im asking y deres no radiation

nice explanation gagar

in case of standing wave condition the charge wont emit the radiation
2πr=nλ condition for standing wave
mv=h/λ de broglie
substituting the values we can get mvr=nh/2Ï€

guy i know abt the assumption and postulate

im just asking the reason for its weird exception

haha!!!!!

Well, i completely agree with MAK, its the basic assumption of Bohr but not justified..!!

somewhat correct...!!!

arey yaar, every teacher teaches d same in d first class of bohr's model... dat stable energy levels is d assumption of bohr to overcome d defects of rutherford model...

n btw... who's dis mak...? thrs no mak existing in dis site... [3] [4] [6]

@subhash,,, arey isiliye toh bohr ko nobel prize mila tha... becuse it is stable [3]

i too dun know exactly... [chem toh waise hi pata nahi... aur upar se itnaaaaa tricky doubt... waise yeh mera class 9 se hi doubt hai :P]

do u mean that why is there no radiation when the electron moves in the same orbit?

Subash ·

magnitude of velocity u mean

in bohrs orbit the electrons r in uniform circular motion.an emr is produced if there is change in the magnitude also.

Subash ·

sum one please correct me if i am wrong

Subash ·

an accelerated charge emits emr rite

if the bohr orbit is circular it is accelerated and so it has to emit emr

then how is it stable sky

skygirl ·

because it is stable there...

I think he means that.
Even I thought of posting the same q
