A) 2000 Å, 3000 Å
B) 1575 Å, 2960 Å
C) 6529 Å, 4280 Å
D) 6552 Å, 4863 Å
Correct Answer: D
Solution :
\[\frac{1}{\lambda }=R\left[ \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right].\] For first wavelength, \[{{n}_{1}}=2\], \[{{n}_{2}}=3\] Þ\[{{\lambda }_{1}}=6563\,{\AA}\]. For second wavelength, \[{{n}_{1}}=2\], \[{{n}_{2}}=4\] Þ \[{{\lambda }_{2}}=4861\,{\AA}\]You need to login to perform this action.
