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.
(Planck was a German physicist who studiedthe electromagnetic spectrum, and how light interacts with matter.) Consider how factors arerelated in this equation; if the frequency is doubled, so is the energy. If the frequency is de-creased by half (50%), energy is decreased by half.
