Photon Energy Formula
The energy carried by a single photon is referred to as photon energy. The photon's electromagnetic frequency is directly proportional to the amount of energy it contains, and consequently the wavelength is inversely proportionate.
The Photon Energy Formula is E = h*f
- Here, h be the Planck constant, Its value is 6.6261 x 10-34J.s
- E be the energy of a photon
- f be the frequency

Planck's Equation
We notice that the light has a wavy quality to it. It refracts, diffracts, and interferes. At a microscopic level, however, it is carried by the photon, a miniscule particle of energy. Planck's equation calculates the energy of a single photon as a small number.
The Planck's equation is E = h*c/λ
- Here, h be the Planck constant, Its value is 6.6261 x 10-34J.s
- E be the energy of a photon
- c is the speed of light
- λ is the wavelength of a photon
The Planck equation uses a Planck constant h equal to connect the frequency of a photon to its energy.Its value is h=6.6261×10−34 J*s. The Planck constant is expressed in the units (energy)*(time), and it can be thought of as a factor for converting energies to frequencies.

Photon Energy Examples
Question 1: Find the the frequency of photon and wavelength when the energy of photon is 5ev.
Solution:
Consider the problem, we have
Photon Energy,E = 5eV
We know the formula to calculate the frequency of the photon Energy is f = E / h * 6.242 * 1018.
Here, h = 6.6261×10-34 Js and c = 299792458 m/s
Substituting the inputs into the above formula, we get
Frequency ,f = 5 / 6.6261 * 10-34 * 6.242 * 1018
Photon frquency(f) = 1208894089132177.2 Hz
As a result,The frequency of the Photon Energy: f = 1209.2 Hz
FAQs on Photon Energy Calculator
1. What is the energy content of a photon?
This equation: E = hv, can be used to calculate the energy of a single photon, where h is Planck's constant and v is velocity. A photon's energy is about equal to 10-19 joules.
2. What factors influence photon energy?
The energy of a photon is determined by the frequency or wavelength of the radiation. The photon energy increases as the frequency rises. The energy of photons increases as the wavelength is reduced.
3. When the wavelength of a photon is doubled, what happens to its energy?
The energy of a photon, according to Einstein's Quantum Theory of Light, is the product of Planck's constant and frequency, hence doubling the wavelength reduces the energy by half.
4. What happens when a photon's energy increases?
Because energy is proportional to frequency, when energy rises, the frequency rises as well and the wavelength shrinks. Because the wavelength is inversely proportional to the energy.
