Min frga var: Vi antar att en gldande jrnstng kan anses vara en absolut svart kropp. Fr vilken vglngd r den spektrala emittansen maximal om jrnstngen har temperaturen 1700 K? Svara med tv vrdesiffror. Jag svarade: Vi anvnder oss av Wiens frskjutningslag max = b / T dr: max = maximala vglngden b r Wiens frskjutningskonstant (2,897 103) T r temperaturen i Kelvin Vi stter helt enkelt in vrdena som vi har: max = (2,897 x 10^-3) / 1700 max 1,7 Den maximala vglngden i tv vrdesiffror r 1,7m Vad tror du
