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.
n. The elementary particle of light and other electromagnetic radiation; the quantum of electromagnetic energy. The photon is the massless, neutral vector boson that mediates electromagnetic interactions.phoÂ·tonâ²ic adj.hoton. n. 1. (Atomic Physics) a quantum of electromagnetic radiation, regarded as a particle with zero rest mass and charge, unit spin, and energy equal to the product of the frequency of the radiation and the Planck constant.
