Electrons in a sample of H-atoms make transition from state n = y to some lower excited state. The emission spectrum from the sample is found to contain only the lines belonging to a particular series.
If one of the photons had an energy of `(0.85 xx (3)/(4))`ev. Then find the value of y

Correct Answer - 8
`(3)/(4)xx0.85ev=13.6xx1^(2)[(1)/(n^(2))-(1)/(y^(2))]" "thereforen=4,y=8`

Electrons in a sample of H-atoms make transition from state n=x to some lower excited state. The emission spectrum from the sample is found to contain

Correct Answer - x=8 We have `DeltaE=3/4xx0.85eV` as energy=0.6375 the photon will belong to brackett series (as for brackett`0.31leEle0.85`) `0.85xx(1-1/4)=13.6(1/4^2-1/n^2)` `0.85(1-1/4)=13.6/16[1/(4/n)^2] :. 4/n=1/2 implies n=8` Hence x=8

Find the quantum of the excited state of electrons in `He^(+)` ion which on transition to first excited state emit photons of wavelengths `108.5 nm`.

Correct Answer - B `1/lambda=R_(H)Z^(2)[1/1^(2)-1/n_(2)^(2)]` `1/(108.5xx10^(-9))=1.09678xx10^(7)xx4[1/2^(2)-1/n_(2)^(2)]` This gives `n_(2)=5`
