A hypothetical atom has two energy levels, with a transition wavelength between them of 580 nm. In a particular sample at 300 K, $4.0 \cdot 10^{20}$ such atoms are in the state of lower energy. (a) How many atoms are in the upper state, assuming conditions of thermal equilibrium? (b) Suppose, instead, that $3.0 \cdot 10^{20}$ of these atoms are “pumped” into the upper state by an external process, with $1.0 \cdot 10^{20}$ atoms remaining in the lower state. What is the maxi-mum energy that could be released by the atoms in a single laser pulse if each atom jumps once between those two states (either via absorption or via stimulated emission)?

The majority of atomic physics questions and solutions that you will find might not deal with your subject directly since the atomic physics equations may not be suitable for your discipline. Likewise, some answers that you will find provided will be related to the lab reports and specific experiments. You can also approach Balmer series equation to determine the spectral line emissions as you focus on the hydrogen atoms. Exploring various atomic physics solutions, make sure that you provide an explanatory paragraph that will explain why you have chosen a certain methodology and what scientific objectives you have set to choose. When you need to work with the
