We will ahve the following:
A harmonic is a wave or signal whose frequency is a whole number, which is a multiple of the frequency of the same reference signal or wave.
a. The number of waves present in a standing wave pattern is 2.
b. One of the frequencies at which an instrument naturally vibates is called a harmonic or a natura frequency.
c. A point on the standing wave pattern which is oscillating rapidly could be a node.
d- The multiplier used to relate one natural frequency to another natural frequecy is the relationship between the speed of the wave ad the wavelenght.
