Photon energy conversion is based on fundamental relationships in quantum physics. The energy of a photon is related to its frequency by Planck's constant (E = hν), and to its wavelength by the speed of light (E = hc/λ). These relationships allow us to convert between different representations of photon energy.
The electron volt (eV) is a convenient unit for atomic and molecular energy scales, where 1 eV equals 1.602×10⁻¹⁹ joules. Wavelength units like nanometers are commonly used in optics, while frequency units are useful in spectroscopy and quantum mechanics. Our converter handles all these relationships accurately.
This tool is essential for researchers working with light sources, analyzing spectral data, designing optical systems, and understanding quantum phenomena. It provides precise conversions using fundamental physical constants, ensuring accuracy across the electromagnetic spectrum from radio waves to gamma rays.
Physical Constants: Conversions use Planck's constant (h) and speed of light (c).
Wavelength Range: Valid for all electromagnetic wavelengths from radio to gamma rays.
Energy Conservation: All conversions preserve the fundamental photon energy.
