JEE Mains · Physics · STD 12 - 12. atoms

Given below are two statements: Statement \(I\) : In hydrogen atom, the frequency of radiation emitted when an electron jumps from lower energy orbit \(\left( E _{1}\right)\) to higher energy orbit \(\left( E _{2}\right)\), is given as \(hf = E _{1}- E _{2}\). Statement \(II\) : The jumping of electron from higher energy orbit \(\left(E_{2}\right)\) to lower energy orbit \(\left(E_{1}\right)\) is associated with frequency of radiation given as \(f\) \(=\left( E _{2}- E _{1}\right) / h\) This condition is Bohr's frequency condition. In the light of the above statements, choose the correct answer from the options given below

  1. A Both statement \(I\) and statement \(II\) are true
  2. B Both statement \(I\) and statement \(II\) are false
  3. C Statement \(I\) is correct but statement \(II\) is false
  4. D Statement \(I\) is incorrect but statement \(II\) is true
Verified Solution

Answer & Solution

Correct Answer

(D) Statement \(I\) is incorrect but statement \(II\) is true

Step-by-step Solution

Detailed explanation

When electron jump from lower to higher energy level, energy absorbed so statement - \(I\) incorrect. When electron jump from higher to lower energy level, energy of emitted photon \(E = E _{2}- E _{1}\) \(hf = E _{2}- E _{1} \Rightarrow f =\frac{ E _{2}- E _{1}}{ h }\) so…
