Question

A magnetostriction oscillator has a frequency of 20kHz. If it produces sound wave of velocity 6.2 x 103 m/s, find the length of ferrite rod.

Answer 1

Answer:

Sound is transmitted from one place to another by means of waves. The character of any wave can be described by identifying two related properties: its wavelength (lambda, λ) or its frequency (f). The unit used to measure the frequency of any wave is hertz. One hertz is defined as the passage of a single wave per second.
