A) \[6563\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[4102\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[4861\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[1215\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: D
Solution :
Wavelength of light \[\frac{1}{\lambda }=R\left( \frac{1}{{{1}^{2}}}-\frac{1}{{{2}^{2}}} \right)\] \[\Rightarrow \] \[\frac{1}{\lambda }=1.097\times {{10}^{7}}\times \frac{3}{4}\] \[\therefore \] \[\lambda =1.215\times {{10}^{-7}}m=1215\overset{\text{o}}{\mathop{\text{A}}}\,\]
