What is the dispersion relation in photons? "(Frequency momentum or etc)
Ah, yes, of course, but the OP asked about photons.malawi_glenn said:lightarrow, why restrict yourself to light? The dispersion relation are for waves, all waves, as far as I have understood it.

A dispersion relation is a mathematical relationship between the frequency and wavelength of a wave, which describes how the wave propagates through a medium.
The dispersion relation for photons describes the relationship between their energy and momentum, which is related to their frequency and wavelength.
The dispersion relation is important because it allows us to understand the properties and behavior of photons, such as their speed and how they interact with matter.
Yes, the dispersion relation can be applied to all types of photons, including visible light, infrared, ultraviolet, and even radio waves.
The dispersion relation is used in various fields such as optics, telecommunications, and spectroscopy to design and analyze devices that use light, such as lenses, fiber optic cables, and sensors. It is also used in the study of cosmology and the behavior of light in the universe.
