and described by the formula: where A is the amplitude of oscillation, f is the frequency, t is the elapsed time, and is the phase of the oscillation. The phase determines or is determined by the initial displacement at time t = 0. A motion with frequency f has period. Two potential ambiguities can be noted:
Incubation Period Shingles is not transmitted from exposure to another infected person so there is no applicable incubation period. Anyone who has recovered from varicella may develop shingles. Mode of Transmission Transmission of the virus occurs through direct contact with the rash or fluid from the lesions.
The typical time from exposure to a person infected with measles to development of the initial symptoms (incubation period) is 10-12 days (the range is seven to 21 days).The rash occurs a few days after the initial symptoms (ranges from seven to 18 days from exposure).Medically Reviewed by a Doctor on 2/6/2015.he typical time from exposure to a person infected with measles to development of the initial symptoms (incubation period) is 10-12 days (the range is seven to 21 days).
