WebJan 18, 2024 · This phenomenon has to do with the nature of light, which is an electromagnetic wave. As it propagates through a material its electric and magnetic fields "disturb" the charged particles that it comes in contact with. These disturbances then cause the particles to radiate light at the same frequency, but with a phase shift. In physics and mathematics, the phase of a periodic function of some real variable (such as time) is an angle-like quantity representing the fraction of the cycle covered up to . It is denoted and expressed in such a scale that it varies by one full turn as the variable goes through each period (and goes through each complete cycle). It may be measured in any angular unit such as degrees or radians, thus increasing by 360° or as the variable completes a full period. fake camera google play
