<\/span> Doppler etkisi nedir?<\/span><\/h2>\n

Doppler etkisi,<\/strong> bir dalgan\u0131n vericisi veya al\u0131c\u0131s\u0131 birbirine g\u00f6re hareket etti\u011finde ortaya \u00e7\u0131kan fiziksel bir olgudur. Daha do\u011frusu Doppler etkisi, verici ile al\u0131c\u0131 aras\u0131ndaki g\u00f6receli hareket nedeniyle dalgan\u0131n g\u00f6r\u00fcn\u00fcr frekans\u0131ndaki de\u011fi\u015fiklikten olu\u015fur.<\/p>\n

\u00d6rne\u011fin Doppler etkisi, bir ambulans sireni \u00e7alarak ileri do\u011fru hareket etti\u011finde ortaya \u00e7\u0131kar. Ambulans ses \u00e7\u0131kararak ileri do\u011fru hareket ediyor; dolay\u0131s\u0131yla Doppler etkisi nedeniyle alg\u0131lanan frekans, ambulans\u0131n hareketsiz olmas\u0131 durumunda alg\u0131layaca\u011f\u0131m\u0131z ses dalgalar\u0131n\u0131n frekans\u0131ndan farkl\u0131d\u0131r.<\/p>\n

A\u015fa\u011f\u0131daki g\u00f6rselde g\u00f6rebilece\u011finiz gibi dalgan\u0131n alg\u0131lanan frekans\u0131, al\u0131c\u0131n\u0131n ambulansa g\u00f6re konumuna ba\u011fl\u0131d\u0131r. Ambulans soldan sa\u011fa do\u011fru hareket etti\u011finden dalga o y\u00f6nde s\u0131k\u0131\u015ft\u0131r\u0131l\u0131r. Yani ambulans\u0131n solunda frekans d\u00fc\u015f\u00fck, dalga boyu y\u00fcksek oldu\u011fundan d\u00fc\u015f\u00fck bir ses alg\u0131lan\u0131yor. Ambulans\u0131n sa\u011f\u0131nda ise frekans y\u00fcksek, dalga boyu k\u00fc\u00e7\u00fck oldu\u011fundan tiz bir ses duyulur. <\/p>\n

Doppler etkisi, ad\u0131n\u0131 bu fenomeni 1842’de ke\u015ffeden Avusturyal\u0131 fizik\u00e7i Christian Andreas Doppler’den alm\u0131\u015ft\u0131r. Daha sonra, 1848’de Frans\u0131z fizik\u00e7i Hippolyte Fizeau ba\u011f\u0131ms\u0131z olarak ayn\u0131 fenomeni elektromanyetik dalgalar i\u00e7in de ke\u015ffetti, bu y\u00fczden buna Doppler etkisi de denir. etki. -Fizeau. <\/p>\n

Art\u0131k Doppler etkisinin ne oldu\u011funu bildi\u011fimize g\u00f6re, kavram\u0131 daha iyi anlamak i\u00e7in bu fiziksel olgunun g\u00fcnl\u00fck \u00f6rneklerine bakal\u0131m.<\/p>\n
