# How to calculate the energy in gamma photons

• Amanuel
In summary, the energy of a gamma photon can be calculated using the formula E = hf, where E is energy in joules, h is Planck's constant (6.626 x 10^-34 J s), and f is the frequency of the photon in hertz. The energy of a gamma photon is directly proportional to its frequency, meaning that as the frequency increases, so does the energy of the photon. The energy of a gamma photon can also be calculated using the formula E = hc/λ, where c is the speed of light (3 x 10^8 m/s) and λ is the wavelength of the photon in meters. In experiments, the energy of a gamma photon is often measured using a gamma spectrometer

how do I calculate the energy of to photons moving in the opposite direction. starting from the same origin.

E = hγ ?

I mean using just the mass invarians of relativity

If you have no data to use as input, a formula will not help. What do you know about these photons or about the process that produced them?

## 1. How do you calculate the energy of a gamma photon?

The energy of a gamma photon can be calculated using the formula E = hf, where E is energy in joules, h is Planck's constant (6.626 x 10^-34 J s), and f is the frequency of the photon in hertz.

## 2. What is the relationship between energy and frequency for gamma photons?

The energy of a gamma photon is directly proportional to its frequency. This means that as the frequency increases, so does the energy of the photon.

## 3. Can the energy of a gamma photon be calculated if only the wavelength is known?

Yes, the energy of a gamma photon can be calculated using the formula E = hc/λ, where c is the speed of light (3 x 10^8 m/s) and λ is the wavelength of the photon in meters.

## 4. How is the energy of a gamma photon measured in experiments?

The energy of a gamma photon is often measured using a gamma spectrometer, which detects and measures the energy of gamma rays emitted by a source. The spectrometer then produces a spectrum that shows the energy distribution of the gamma photons.

## 5. Is there a maximum energy for gamma photons?

No, there is no maximum energy for gamma photons. These photons can have a wide range of energies, with some having incredibly high energies in the teraelectronvolt (TeV) range.
