Q

Gesamtenergieabgabe des schwarzen Strahlers pro Zeit und Fläche

A

Boltzmannsches T^4 Gesetz

Iges (T)=epsilon x sigma X T^4
P = epsilon x sigma x A x T^4

Ergibt sich aus planckschem strahlungsgesetz

Q

Licht als Welle

A

y = y0sin(kx - wt - phi)

y0 - Amplitude der Welle 
k - wellenzahl (räumliche Periodizität)
w - Kreisfrequenz (zeitliche)
w = 2Pi x f 
Lambda = 2pi / k
