Oblicz dlugosc fali swiatla, ktorego fotony maja energie 1,6 eV?

 E = 1,6 eV 1 eV = 1,602 *10⁻¹⁹ J E = 1,6 *1,602 *10⁻¹⁹ = 2,56 *10⁻¹¹ J h = 6,63 *10⁻³⁴ J*s c = 3 *10⁸ m/s λ = ? [latex]E = frac{h*c }{lambda} [/latex] [latex]lambda = frac{h*c}{E} [/latex] [latex]lambda = frac{6,63 *10 ^{-34}J * s * 3 *10^8 frac{m}{s} }{2,56 *10 ^{-11} J} lambda = 7,77 *10 ^{-15} m[/latex]
