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.
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
Switch tool with the current settings for photon energy (E) or wavelength (λ), and calculate frequency (f) of an em wave instead. Calculate the wavelength of an electromagnetic wave in a vacuum by entering a value for the corresponding energy per photon for the em wave.
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.
Need a quick unit conversion from wavelength (nm) to photon energy (eV)? Need to convert flux (ph/s) to average power ( m W)? Simply enter the known value in the boxes below, and the calculator will provide the equivalent value in the appropriate unit.
18 Φεβ 2023 · In our photon energy calculator you will learn: What is a photon, and why are they so important; The equation for the energy of a photon: how to calculate the energy from the frequency; How to calculate the energy from the wavelength; and; How to calculate the number of photons in a light beam.
3 Οκτ 2024 · Photon energy can be calculated using Planck's equation: \ [ E = h \cdot \nu \] or. \ [ E = \frac {h \cdot c} {\lambda} \] Where: E is the photon energy. h is Planck's constant (\ (6.62607015 \times 10^ {-34}\) J·s). \ (\nu\) is the frequency of the photon. c is the speed of light (\ (299792458\) m/s). \ (\lambda\) is the wavelength of the photon.
