Question 399: Atoms & Nuclei

Question

X different wavelengths may be observed in the spectrum from a hydrogen sample if the atoms are exited to states with principal quantum number n = 6 ? The value of X is ______________.

Accepted Answer

No. of different wavelengths = $${{n(n - 1)} \over 2}$$
$$ = {{6 	imes (6 - 1)} \over 2} = {{6 	imes 5} \over 2} = 15$$
