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 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:

1. Statement I and statement II are true
2. Both statement I and statement II are false
3. Statement I is correct but statement II is false
4. Statement I is incorrect but statement II is true

Correct answer: Statement I is incorrect but statement II is true

Solution

Statement I is incorrect because the correct relationship for the frequency of emitted radiation when an electron transitions from a higher energy level to a lower one is given by hf = E2 - E1, not E1 - E2. Statement II is correct as it accurately describes the frequency associated with the transition from a higher energy orbit to a lower energy orbit according to Bohr's frequency condition.
