Atoms - Result Question 17
18. An electron in hydrogen atom makes a transition $n_1 \to n_2$ where $n_1$ and $n_2$ are principal quantum numbers of the two states. Assuming Bohr’s model to be valid the time period of the electron in the initial state is eight times that in the final
Show Answer
Answer:
Correct Answer: 18. (a)
Solution:
- (a) $\because T \propto n^{3}$
$\frac{T_1}{T_2}=\frac{8 T_2}{T_2}=(\frac{n_1}{n_2})^{3}$
Hence, $n_1=2 n_2$
