Web7 mei 2015 · We can solve this for the wavelength, l = h c / E . where h = 6.626 x 10 -34 J-s, and c = 3 x 10 8 m/s. We convert our energy E= 2.55 ev into Joules using 1 eV = 1.6x10 -19 J. This gives an energy of E = 4.08 x 10 -19 J. We then find a wavelength of l = ( (6.626 x 10 -34) x (3 x 10 8 )) / (4.08 x 10 -19) l = 4.87 x 10 -7 m.
