This is Omni's wavelength to energy calculator, a tool that instantly calculates a photon's energy from its wavelength. By using Planck's equation, this tool will help you determine a photon's energy in joules (J), electronvolts (eV), or its multiples.
21 Οκτ 2024 · To calculate wavelength from the energy of a photon: Convert the photon's energy into joules. Divide the speed of light, equal to 299,792,458 meters per second, by the photon's energy. Multiply the resulting number by Planck's constant, which is 6.626×10 −34 J/Hz.
eV/particle to J/mol Conversion. The abbreviation for eV/particle and J/mol is electron volt per particle and joule per mole respectively. 1 eV/particle is 96492 times bigger than a J/mol.
(eV) The electron volt is the energy that we would give an electron if it were accelerated by a one volt potential difference. 1 eV = 1.602 x 10-19 J. This term is most often used by physicists and electrochemists.
29 Ιουλ 2024 · To calculate the energy of a photon, follow these easy steps: If you know the wavelength, calculate the frequency with the following formula: f =c/ λ where c is the speed of light, f the frequency and λ the wavelength. If you know the frequency, or if you just calculated it, you can find the energy of the photon with Planck's formula: E = h × f
The energy of a photon can be calculated using the following formula: E = hc / λ. Where: E is the energy of the photon (in joules). h is the Planck 's constant (6.62607015 × 10 -34 m 2 kg/s). c is the speed of light (approximately 3 × 10 8 m/s). λ is the wavelength of the photon (in meters).
When used as a unit of energy, the numerical value of 1 eV in joules (symbol J) is equal to the numerical value of the charge of an electron in coulombs (symbol C). Under the 2019 revision of the SI, this sets 1 eV equal to the exact value 1.602 176 634 × 10 −19 J. [1]
