CSDS 103 Exam #1 practice test - part 3

The pitch of sound is determined by the frequency of vibration of the sound waves that produce them.

In a ___________ wave the movement of the medium moves in the same direction of the wave movement.

In a ____________, the particles of the medium move perpendicular (right angles) to the direction of the wave

The resonant frequency of an object depends on its _____ and what it is made out of, and every object has a natural frequency.

What is the frequency where the mass is most easily set into vibrations at which the magnitude of the vibration decays the slowest.

An example of a sharply tuned resonator is a telephone earpiece

A sharply tuned resonator has a limited number of frequencies.

_______ vibrations have no pattern and are mostly random of various sorts

The __________ frequency is the lowest frequency of vibration in the spectrum of a complex periodic wave.

In a _________, the amplitude is plotted as a function of frequency at instant in time.
