Bohr Model: Orbits, Speed & Angular Momentum

Given below are two statements:

Statement I: In hydrogen atom, the frequency of radiation emitted when an electron jumps from lower energy orbit (E1) to higher energy orbit (E2), is given as hf = E1 $-$ E2

Statement II: The jumping of electron from higher energy orbit (E2) to lower energy orbit (E1) is associated with frequency of radiation given as f = (E2 $-$ E1)/h

This condition is Bohr's frequency condition.

In the light of the above statements, choose the correct answer from the options given below:

Show answer and solution

Answer: (d)

Statement I: absorption from $E_1$ to $E_2$ needs $hf = E_2 - E_1$ ; $E_1 - E_2$ is negative. False.
Statement II: emission from $E_2$ to $E_1$ gives $f = \dfrac{E_2 - E_1}{h}$ , Bohr's frequency condition. True.
So the answer is (d).
