In this chapter, we explore how motion can affect the perceived frequency of waves, with significant implications for spectroscopy. We cover the broadening and shifting of atomic line frequencies due to atomic movement and investigate the roles of velocity and temperature in these phenomena. Key topics include the Doppler effect, Doppler broadening, the Maxwell-Boltzmann velocity distribution, and the Equipartition Theorem. Additionally, the chapter discusses the application of the Doppler effect in astronomy.
