JEE Mains · Physics · STD 12 - 12. atoms
Find the ratio of energies of photons produced due to transition of an election of hydrogen atom from its \((i)\) second permitted energy level to the first level, and \((ii)\) the highest permitted energy level to the first permitted level.
- A \(3: 4\)
- B \(4: 3\)
- C \(1: 4\)
- D \(4: 1\)
Answer & Solution
Correct Answer
(A) \(3: 4\)
Step-by-step Solution
Detailed explanation
\(E _{ n }=\frac{-13.6}{ n ^{2}}\,ev\) \(\Rightarrow \frac{ E _{2}- E _{1}}{ E _{\infty}- E _{1}}=\frac{13.6\left(1-\frac{1}{4}\right)}{13.6}=\frac{3}{4}\)
