Atoms And Nuclei Question 296
Question: Electrons are bombarded to excite hydrogen atoms and six spectral lines are observed. If $ E_{g} $ is the ground state energy of hydrogen, the minimum energy the bombarding electrons should posses is
Options:
A) $ \frac{8E_{g}}{9} $
B) $ \frac{15E_{g}}{16} $
C) $ \frac{35E_{g}}{36} $
D) $ \frac{48E_{g}}{49} $
Show Answer
Answer:
Correct Answer: B
Solution:
- To obtain 6 spectral line, as electron must be excited to fourth orbit with energy $ \frac{E_{g}}{16}, $ so that the difference is $ \frac{15E_{g}}{16}, $
