Refraction
of light: the frequency of incident light close to the intrinsic
vibration frequency of electrons, it will further the internal objects,
causing the electron micro-vibration, the energy passed to the nucleus,
nuclear and then to make waves with frequencies revealing the original
object, but this process requires a certain of time, allowing light and
air at the same time spread in the medium. Because at different speeds,
will be the interface to form a break point. The emergence of rainbow
after the rain, that is, the formation of atmospheric refraction of
sunlight. |
