Jaka energie ma fala o dlugosci 600nm (nanometry) ?

[latex] E_{f} = frac{hc}{lambda} [/latex] [latex]= frac{6,6* 10^{-34}*3* 10^{8} }{6* 10^{-7} } =3,3* 10^{-19}[J] [/latex] (są to wartości przybliżone)

[latex]dane:\lambda = 600 nm = 600*10^{-9} m= 6*10^{-7} m\h = 6,63*10^{-34} J*s\c = 3*10^{8}frac{m}{s}\szukane:\E_{f} = ?[/latex] [latex]E_{f} = c*frac{h}{lambda}\\E_{f} = 3*10^{8}frac{m}{s}*frac{6,63*10^{-34}J*s}{6*10^{-7}J}}=3,315*10^{-19} J\\E_{f} approx 3,3*10^{-19} J[/latex]
