SUMMARY
The value of the constant, 1240, in the Duane-Hunt relation is verified through the equation E(eV) = 1240/lambda(nm), which relates the energy of a photon to its wavelength. To confirm this constant, one must utilize Planck's constant and the speed of light in a vacuum. The verification process involves understanding the conversion between energy in electron-volts and Joules, as well as the relationship between wavelength and frequency. Key constants such as Planck's constant and the speed of light are essential for this calculation.
