The velocity of waves on a string is 95.0 m/s. If the frequency of standing waves is 160 Hz, how far apart are two adjacent nodes? If two successive overtones of this vibrating string are 240 Hz and 320 Hz, what are the frequency of the fundamental and the length of the string?
Solutions
Expert Solution
velocity v = 95 m/s
(a)
frequency n = 160 Hz
Wavelength λ = v/n
=
95/160 = 0.593 m
Distance between two adjacent nodes d = λ/2 = 0.296 m
The speed of waves on a string is 97 m/s. If the frequency of
standing waves is 485Hz, how far apart are the two adjacent
nodes?

Standing waves on a guitar string form when waves traveling down the string reflect off a point where the string is tied down or pressed against the fingerboard.The entire series of distortions may be superimposed on a single figure, like this (Intro 2 figure) , indicating different moments in time using traces ofdifferent colors or line styles.What is the wavelength λ of the standing wave shown onthe guitar string?
n the Group Work, we examine standing waves on a string. In
order to calculate the velocity of the wave, what two properties do
we need to know?

string, these are the DENSITY and the YOUNG'S MODULUS of the
string.

Transverse waves on a string have wave speed 8.00 m/s, amplitude
0.0700 m, and wavelength 0.320 m. These waves travel in the
x direction, and at t = 0 the
x = 0 end of the string is at y = 0 and moving
downward.

To see how two traveling waves of the same frequency create a standing wave.
Consider a traveling wave described by the formula
y1(x,t)=Asin(kx??t).
This function might represent the lateral displacement of a string, a local electric field, the position of the surface of a body of water, or any of a number of other physical manifestations of waves.
Part C
Find ye(x) and yt(t). Keep in mind that yt(t) should be a trigonometric function of unit amplitude.
