How do you convert Angstrom to eV? 1 Angstrom (A) corresponds to 12398 eV (or 12.398 keV), and the relationship is inverse, according to Ephoton = hν = hc/λ. So, E(eV) = 12398/λ(A) or λ(A) = 12398/E(eV) = 12.398/E(keV). Note that you can combine the above to facts to relate wavelengths to temperatures. How do […]
