Atomic Structure Question 419
Question: Find the value of wave number $ ~( \overline{v} ) $ in terms of Rydberg’s constant, when transition of electron takes place between two levels of $ H{e^{+}} $ ion whose sum is 4 and difference is 2.
Options:
A) $ \frac{8R}{9} $
B) $ \frac{32R}{9} $
C) $ \frac{3R}{9} $
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
- $ n_1+n_2=4;n_2-n_1=2;\therefore n_1=l,n_2=3 $
$ \overline{v}=R{{(2)}^{2}}[ \frac{1}{1^{2}}-\frac{1}{3^{2}} ]=\frac{32R}{9} $
