If photons had non zero rest mass, which would be the relationship between energy and frequency?
A photon is a massless particle, meaning that it has no rest mass. It only has energy and momentum, which are related to its frequency and wavelength.
A photon's mass and frequency are inversely proportional. This means that as the frequency increases, the mass decreases, and vice versa. This relationship is described by the famous equation E=mc2, where E represents energy, m represents mass, and c represents the speed of light.
No, all photons have the same mass of zero. The concept of mass only applies to particles that are at rest, and since photons are always moving at the speed of light, they do not have a rest mass.
A photon's frequency is determined by its energy. The higher the energy, the higher the frequency. This can be seen in the electromagnetic spectrum, where photons with higher frequencies have higher energies and are more energetic.
The unit of frequency for a photon is the hertz (Hz), which represents the number of cycles or oscillations per second. This unit is used to measure the frequency of all electromagnetic radiation, including photons.
