Answer:f a wave has frequency, f, of 3 Hz, its period, T, is 13s . The wavelength, λ , is 5 meters. That means that in the time of one period, the wave travels 5 m. Note: the unit Hz is equivalent to what it was called 100 years ago, cyclessecond(also cps) .
Explanation:amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. ... For a longitudinal wave, such as a sound wave, amplitude is measured by the maximum displacement of a particle from its position of equilibrium.
