CO OZNACZA SŁOWO TYNDALL EFFECT
Efekt Tyndalla
Efekt Tyndalla, znany również jako rozproszenie Tyndalla, jest lekki rozpraszanie cząstek w koloidie lub cząstkach w drobnej zawiesinie. Nazwa pochodzi od 19-wiecznego fizyka Johna Tyndalla. Jest podobny do rozproszenia Rayleigha, gdyż natężenie rozproszonego światła zależy od czwartej mocy częstotliwości, więc niebieskie światło jest rozproszone znacznie silniej niż czerwone światło. Przykładem codziennego życia jest niebieski kolor, jaki czasami widać w dymie emitowanym przez motocykle, w szczególności maszyny dwusuwowe, w których spalony olej silnikowy dostarcza cząstki. Pod efektem Tyndalla światło o większej długości fali jest bardziej przenoszone, podczas gdy światło rozproszone jest bardziej odbite przez światło o krótszej długości fali. Analogią do tej zależnej od długości fali jest to, że fale elektromagnetyczne o długiej fali, takie jak fale radiowe mogą przechodzić przez ściany budynków, a fale elektromagnetyczne takie jak fale świetlne są zatrzymywane i odbijane przez ściany.
Definicja słowa Tyndall effect w słowniku
Definicja efektu Tyndalla w słowniku jest zjawiskiem, w którym światło jest rozpraszane przez cząsteczki materii na swojej ścieżce. Umożliwia widoczność wiązki światła dzięki oświetleniu cząsteczek pyłu itp.
