Doppler effect and its applications

Christian Doppler prvi je proučavao frekvencije zvuka te uočio da, ako nam se izvor zvuka približava ili udaljava, ne čujemo istu frekvenciju koju je izvor odaslao. Uspio je opisati i dokazati navedenu hipotezu javnim pokusom još u 19. st. Promatrajući iz perspektive tog vremena nikada ne bismo mogli pretpostaviti da će to otkriće doživjeti tako raznoliku primjenu i steći toliko veliku važnost u mnogim područjima fizike, kao što su astronomija, medicina, navigacija i mnoga druga područja. U ovom radu, uz kratak teorijski uvod i matematički prikaz same pojave Dopplerovog efekta, bit će opisan način na koji se on primjenjuje u navedenim područjima.Christian Doppler was the first one who studied sound frequencies and noticed that, if the source is coming towards us or going away from us, we do not hear the same frequency as the source emitted. He managed to describe and demonstrate this hypothesis by public experiment in the 19th century. From the perspective of that time, it could never be assumed that this discovery would have a wide range of applications and gain great importance in many areas of physics. The present application of Doppler effect is very broad and it is used in astronomy, medicine, navigation and many other areas. In this work, a short theoretical introduction and matematics from Doppler effect will be explained, as well as its application in different areas
