Photon energy is the energy carried by a single photon. The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy.
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.
Explain the relationship between the energy of a photon in joules or electron volts and its wavelength or frequency. Calculate the number of photons per second emitted by a monochromatic source of specific wavelength and power.
29 Ιουλ 2024 · The energy of a single photon of green light of a wavelength of 520 nm has an energy of 2.38 eV. You can use the photon energy calculator to explore further the relationship between the photon energy and its frequency or wavelength.
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.
9 Σεπ 2022 · Each photon of this wavelength has an energy of 1.986 x 10 -18 joules, so be sure to put on your sunscreen to avoid skin damage from the barrage of these ultraviolet photons! The equation can be rewritten to calculate wavelength (and frequency), speed of light and Plank constant.
The energy of a photon, which is the energy of the light, can be calculated using the following two formulas: The second formula is derived from the first by using the relationship between the frequency (ν), wavelength (λ), and speed of light (c) Plank’s constant:
