Wavelength

The energy E, frequency ν, and wavelength λ of a photon are related by E = h ν = h c λ = 4.135 667 696 × 10 − 15 e V / H z × 299 792 458 m / s λ {\displaystyle E=h\nu ={\frac {hc}{\lambda }}={\frac {\mathrm {4.135\ 667\ 696\times 10^{-15}\;eV/Hz} \times \mathrm {299\,792\,458\;m/s} }{\lambda }}} where h is the Planck constant, c is the speed of light. This reduces to E = 4.135 667 696 × 10 − 15 e V / H z × ν = 1 239.841 98 e V ⋅ n m λ. {\displaystyle {\begin{aligned}E&=4.135\ 667\ 696\times 10^{-15}\;\mathrm {eV/Hz} \times \nu \\&={\frac {1\ 239.841\ 98\;\mathrm {eV{\cdot }nm} }{\lambda }}.\end{aligned}}} A photon with a wavelength of 532 nm (green light) would have an energy of approximately 2.33 eV. Similarly, 1 eV would correspond to an infrared photon of wavelength 1240 nm or frequency 241.8 THz.
