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.
Called also sphygmic period. gestation period see gestation period. incubation period see incubation period. isoelectric period the moment in muscular contraction when no deflection of the galvanometer is produced. latency period. 1. latent period. 2. latency stage.latent period a seemingly inactive period, as that between exposure to an infection and the onset of illness (incubation period) or that between the instant of stimulation and the beginning of response (latency, def. 2).alled also sphygmic period. gestation period see gestation period. incubation period see incubation period. isoelectric period the moment in muscular contraction when no deflection of the galvanometer is produced. latency period. 1. latent period. 2. latency stage.
