do dis iron emits K X-ray of energy 6.4 keV & calcium emits K X-ray of energy 3.69 keV calculate d times taken by an iron K photon & a calcium K photon to cross thru a distance of 3km A radio activ sample at any instant has its disintegration rate 5000 disintegrations/minute . after 5 minutes d rate is 1250 disintegrations/min d decay constant [per minute] is [ ans: 0.1ln2] A hydrogen atom in state n=6 makes 2 successive transitions & reaches d ground state. in d 1st transition a photon of 1.13eV is emmitted a)find d energy of d photon emmitted in d 2nd transition b)what is d value of n in d intermediate state?

A radio activ sample at any instant has its disintegration rate 5000 disintegrations/minute . after 5 minutes d rate is 1250 disintegrations/min d decay constant [per minute] is     [ ans: 0.1ln2]  
 
A hydrogen atom in state n=6 makes 2 successive transitions & reaches d ground state. in d 1st transition a photon of 1.13eV is emmitted
a)find d energy of d photon emmitted in d 2nd transition
b)what is d value of n in d intermediate state?
