Gamma
From Wikipedia, the free encyclopedia
Gamma (uppercase Γ, lowercase γ) is the third letter of the Greek alphabet. In the system of Greek numerals it has a value of 3. It was derived from the Phoenician letter Gimel Image:Phoenician gimel.png. Letters that arose from Gamma include the Roman C and G and the Cyrillic letters Ge Г and Ghe Ґ.
In Modern Greek, it represents either a voiced velar fricative /ɣ/ or a voiced palatal fricative /ʝ/. In Ancient Greek, it represented a voiced velar stop /ɡ/. Before velars, it represents a velar nasal /ŋ/ in Modern as well as Ancient Greek, and a double gamma represents a prenasalized voiced velar stop (/ŋɡ/).
[edit] Use as a symbol or a term
Gamma is often used to denote a variable in mathematics and physics. In certain areas it has a specific meaning, such as representing gamma radiation.als:Γ ar:غاما (حرف إغريقي) arc:Γ ast:Gamma br:Gamma (lizherenn) bg:Гама (буква) ca:Gamma cy:Gamma da:Gamma (bogstav) de:Gamma el:Γάμμα es:Γ eu:Gamma (greko) fr:Gamma ga:Gáma gd:Gamma gl:Gamma ko:Γ id:Gamma (huruf Yunani) it:Gamma (lettera) he:גמא (אות) ka:გამა (ასო) sw:Gamma ht:Γ ku:Gamma la:Gamma hu:Gamma ms:Gama nl:Gamma (letter) ja:Γ no:Gamma nn:Gamma nds:Gamma pl:Gamma pt:Γ ru:Гамма (буква) sk:Gama (grécke písmeno) sl:Gama sr:Гама fi:Gamma sv:Gamma th:แกมมา tr:Γ zh:Γ
