A) 3
B) 2
C) 6
D) 10
Correct Answer: C
Solution :
[c] \[{{E}_{1}}=\frac{12400}{975}=12.69eV\] Number of spectral \[lines=\frac{n\,(n-1)}{2}\] \[\Delta \,E=13.60-12.69\] \[\Delta \,E=0.90eV\] \[{{n}^{2}}=\frac{13.6}{\Delta E}=\frac{13.6}{0.9}\] \[{{n}^{2}}=15.8\sim 16\] \[n=4\] Number of spectral line \[=\frac{4\,(4-1)}{2}=6\]You need to login to perform this action.
