The concept of transience and intermittency can be vague. âMicroscopic colitis flare-ups vary in length and intensity from patient to patient,â Dr. Fine says. âDiet, exercise, sleep patterns, stress, and many other factors can affect a flare-up. It can take weeks or years to heal.
A photon is the quantum of electromagnetic radiation that describes the particle properties of an electromagnetic wave. The energy of a photon is given by the equation E = hf, where E is energy, h is Planck's constant, and f is frequency. This equation tells us that as the frequency of radiation increases (wavelength decreases), the photon energy increases.
This isn't true in the particle physics sense, usually. The energy carried by that photon has to be accounted for, as does its momentum and angular momentum. But photon number is not a conserved quantity the way that energy or (for instance) electric charge are. A photon really is just a way of looking at disturbances/excitations in the electric field, and so its destruction just represents that energy that was present in the field has been moved into some other mode.
