Atoms And Nuclei Question 428
Question: The Rydberg constant R for hydrogen is
Options:
A) $ R=-( \frac{1}{4\pi {\varepsilon_{0}}} ).\frac{2{{\pi }^{2}}me^{2}}{ch^{2}} $
B) $ R=( \frac{1}{4\pi {\varepsilon_{0}}} ).\frac{2{{\pi }^{2}}me^{4}}{ch^{2}} $
C) $ R={{( \frac{1}{4\pi {\varepsilon_{0}}} )}^{2}}.\frac{2{{\pi }^{2}}me^{4}}{c^{2}h^{2}} $
D) $ R={{( \frac{1}{4\pi {\varepsilon_{0}}} )}^{2}}.\frac{2{{\pi }^{2}}me^{4}}{ch^{3}} $
Show Answer
Answer:
Correct Answer: D
Solution:
- $ R=\frac{2{{\pi }^{2}}k^{2}e^{4}m}{ch^{3}}={{( \frac{1}{4\pi {\varepsilon_{0}}} )}^{2}}\frac{2{{\pi }^{2}}me^{4}}{ch^{3}} $
