How the Answer is Derived

The principle behind the Energy to Wavelength Calculator is based on the relationship between energy and wavelength as derived from Planck's equation. According to this equation, energy is inversely proportional to wavelength. The calculator first converts the provided energy into Joules if the input is in electron volts (eV) or kilo-electron volts (keV). This ensures the energy value is standardized. The calculator then uses a constant value, known as Planck's constant, and the speed of light to determine the wavelength. The resulting wavelength is expressed in meters, allowing for convenient and consistent results.
