Energy and radiation wavelength

NB: this page is an appendix to the
Errante's hertzian radiation theorem.

  Hertzian radiation and the Hallwachs-effect, better known as the photovoltaic effect.

  Hertzian radiation studies deliver a major blow to the
antimatter theory origin.

Radiation spectrum

Frequency / Wavelength / Energy Calculator


Frequency and wavelength of radiations are related to one another through the speed at which light travels.

Equation: f * λ = c
Equation: E = hc/λ

where:
f = frequency in Hertz (Hz = 1 cycle/sec)
λ = wavelength in meters (m)
c = the speed of light (approximately equal to 3*108 m/s)
E = energy in electron Volts (eV)
h = Planck's constant (6.626068 × 10-34 m2kg/s)

To convert wavelength to frequency enter the wavelength in microns (μm) and press "Calculate f and E". The corresponding frequency will be in the "frequency" field in GHz.

OR enter the frequency in gigahertz (GHz) and press "Calculate λ and E" to convert to wavelength.
Wavelength will be in μm.

OR enter the energy in eV and click "Calculate λ and F" and the values will appear in the corresponding fields.
