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.
De Broglie started with the fact that light acts as both a particle and a wave. In many ways light acts as a wave, with a characteristic frequency, wavelength, and amplitude.Einstein argued, however, that light carries energy as if it contains discrete photons or packets of energy.hen the mass of an object is very small, however, the wave properties can be detected experimentally. De Broglie predicted that the mass of an electron was small enough to exhibit the properties of both particles and waves.
