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.
Imagine the sun to be a spherical gun shooting photons in all directions. These photons travel at the speed of light in straight lines, and can be characterised as 'rays of light'. What it means to say that light takes approx. 8 minutes to reach the earth from the sun is that these photons take approx. 8 minutes to travel the distance between the earth and the sun at their speed (the speed of light).
