Current Question (ID: 20891)

Question:

$\text{Given below are two statements:}$ $\text{Statement I:}$ \quad n_1 \rightarrow n_2 \quad h\nu = (E_2 - E_1) \text{ absorbs a photon.}$ $\text{Statement II:}$ \quad n_2 \rightarrow n_1 \quad h\nu = (E_2 - E_1) \text{ = emitted a photon.}$ $\text{In the light of the above statements, choose the correct answer from the option given below:}$

Options:

1. $\text{Both Statement I and Statement II are true.}$
2. $\text{Both Statement I and Statement II are false.}$
3. $\text{Statement I is true but Statement II is false.}$
4. $\text{Statement I is false but Statement II is true.}$

Solution:

$\text{Hint: Transition from high energy level to lower energy level photon is released}$ $\text{In this process absorbed \& emitted photons have equal energy.}$
