To solve the problem, we need to determine the principal quantum number of the initially excited electrons in a sample of hydrogen gas that emits photons after being irradiated with a specific energy. Let's break down the solution step by step. ### Step 1: Understand the Photon Emission The problem states that the hydrogen gas emits three different photons from two excited states. This implies that there are transitions occurring between energy levels. ### Step 2: Use the Formula for Photon Emission The number of different photon emissions (transitions) from a given excited state can be calculated using the formula: \[ ...
