Concept explainers
To calculate: The wavelength of laser needed to study the energy difference between
Answer to Problem 52A
The wavelength of laser is
Explanation of Solution
Given info:
Each photon has half the energy needed to excite the atoms from the ground state to the desired state.
The transition from
Formula used:
The energy of
Where
Energy of photon emitted:
where
Calculation:
As per problem,
Calculate the energy of the level
Calculate the energy of the level
The energy difference between the two levels is
Each photon in the laser has half the excitation energy.
That is, energy of the photon
Therefore, wavelength of laser is given by
Substitute the values,
Conclusion:
Thus, the wavelength of laser is
