Nonspecific fever. Kids infected with coxsackievirus usually establish an unexpected fever that lasts about 3 days. Often the fever comes in two waves â it is there for a day or two, disappears for a couple of days, then returns for about 3 days.
Albert Einstein proposed the idea the light exists of quanta of energy that he called photons.
Definition [edit]. In 1924 a French physicist Louis de Broglie assumed that for particles the same relations are valid as for the photon: where and are the energy and momentum of the photon, and are the frequency and wavelength of the photon, is the Planck constant, is the speed of light.xplanation of the de Broglie wave through the standing waves inside the particles is also described in the article. In addition, in the article is assumed that inside a particle there is a rotary electromagnetic wave.
