The following three questions relate to the following
information: The fundamental frequency of a string 2.40 m long,
fixed at both ends, is 22.5 Hz.
What is the wavelength of the wave in the string at its
fundamental frequency? (a) 0.11 m (b) 1.20 m (c) 2.40 m (d) 4.80 m
17.
The frequencies of the first two overtones that may be formed by
this length of string are (a) 45 Hz and 67.5 Hz (b) 45 Hz and 90 Hz
(c) 22.5 Hz and 45 Hz (d) 67.5 Hz and 90 Hz 18. The speed of the
wave in this string is (compare with the velocity of sound in air :
346 m s−1 ), (a) 54 m s−1 (b) 108 m s−1 (c) 216 m s−1 (d) 346 m
s−1
