SCI-150 Quiz 3 || CORRECTLY SOLVED!!
the lowest frequency produced by any instrument is called what? correct answers fundamental
frequency
the fundamental frequency is also called what? correct answers the first harmonic
the first harmonic or fundamental frequency has how many waves? correct answers one half
wave
what is the shape of a complete wave? correct answers it starts at the rest position, rises to a
crest, returns to rest, drops to a trough, and finally returns to the rest position.
does a standing wave pattern consist of crests and troughs? correct answers no, because it is the
interference of two waves that produce nodes and antinodes
for the first harmonic of a guitar string, the length of the wave is ________ times the length of
the string correct answers the length of the wave is TWICE the length of the string
how is the second harmonic of a guitar produced? correct answers by adding one more node
between the ends of a guitar string. (when one node is added, an antinode must be added as well)
()
()
in a second harmonic, how many nodes and antinodes are there? correct answers there are three
nodes and two antinodes
in a second harmonic in a guitar, how many waves are there? correct answers one full wave
within the length of the guitar string
how is the third harmonic produced? How many nodes and antinodes are there? correct answers
adding one more node (and an antinode) at the end of the guitar string (four nodes in total, three
antinodes)
how many waves are in the third harmonic? correct answers one and a half (3 halves) waves
within the length of a guitar string
what is the length-wavelength relationship for the fundamental frequency of a guitar string?
(third harmonic) correct answers there are three halves of a wave within the length of a string
if the number of waves in a string is known, what can we determine? correct answers an equation
relating the wavelength of the standing wave pattern to the length of the string
for the first harmonic, what is the length-wavelength relationship? correct answers wavelength =
(reciprocal of number of halves of waves in string X the length of the string)
