The unit "Hz" is short for hertz, named after the German physicist Heinrich Hertz (1857 – 94). when? Amplitude, Frequency, wavelength, and velocity are the characteristic of any wave. A more mathematically useful way to write 2 Hz is 2 s –1. Other animals can hear sound at different frequencies beyond this range; dogs, for instance, can hear a whistle at higher frequencies for us to hear. = 1/T. For a constant wavelength, Increase in frequency will increase in velocity of the wave. Answer. In the common case, the velocity of a sound wave does not depend on the frequency. The wavelength of a sound is the distance between adjacent identical parts of a wave—for example, between adjacent compressions as illustrated in .The frequency is the same as that of the source and is the number of waves that pass a point per unit time. The wavelength of sound is the distance between the analogous points of two successive waves. Sound waves travel at the same speed in a medium such as air, regardless of the frequency of the sound. In a dispersive medium there will be a functional relation between frequency and phase velocity. Frequency And Velocity Relation. Amplitude—distance between the resting position and the maximum displacement of the wave; Frequency—number of waves passing by a specific point per second; Period—time it takes for one wave cycle to complete; In addition to amplitude, frequency, and period, their wavelength and wave velocity also characterize waves.
