In this work, we discuss the determination of the distance to the LargeMagellanic Cloud (LMC) using the Leavitt Law, utilizing the public catalog ofClassical Cepheid Variable stars from the observational project OGLE-IV (TheOptical Gravitational Lensing Experiment Collection of Variable Stars),consisting of 4709 stars in the Large Magellanic Cloud. To determine thepulsation period of Cepheid Variable stars, we employ the computationalalgorithm \textit{Lomb-Scargle periodogram} modified for our data.Additionally, with the calculation of the period, we can derive aperiod-luminosity relation for Cepheid Variables in the Large Magellanic Cloudand, using an independent calibration distance, deduce their distance moduli.We also discuss some general theoretical concepts of the physical mechanismbehind the oscillation of variable stars.
