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.
What Is a Laser? The word laser is an acronym, which stands for light amplification by stimulated emission of radiation. In simpler terms, a laser is a single-wavelength (one color of light) source of high-energy light, which can be accurately focused to transmit that light on to a very small area.
