The color of a star is closely related to its temperature. As the temperature of a star changes, so does its color. This relationship is described by a principle known as Wien's law, which states that the wavelength at which a star emits the most light is inversely proportional to its temperature. When we talk about the color of stars, we often refer to their spectral classification, which is a system that categorizes stars based on their temperatures and spectral features. The most commonly use

SOLVED:Consider a gas of neutral hydrogen atoms, as in Example 1.3 from "The Classification of Stellar Spectra". (a) At what temperature will equal numbers of atoms have electrons in the ground state and in the second excited state (n=3) ? (b) At a temperature of 85,400 K, when equal numbers (N) of atoms are in the ground state and in the first excited state, how many atoms are in the second excited state (n=3) ? Express your answer in terms of N (c) As the temperature T →∞, how will the electro
