Suppose that the frequency of an ideal spring at the first harmonic is 20.0 Hz and the wavelength of the wave is 4.0 m. At the fourth harmonic, what would be the wavelength, the frequency, and the speed of the wave? The frequency of the standing wave when there is one loop is called the fundamental frequency of the first harmonic. In general, what statement can be made about the degree to which the frequency at each of the harmonics...

The third harmonic of a guitar string produces a note with a frequency of 330 Hz from a string with a linear mass density of 4.47*10-3 kg/m. The length of the guitar string is 0.65 meters. Draw a picture of the standing wave described above. Label the nodes and antinodes. Determine the wavelength of the standing wave that produces this note. What is the length of the guitar string (just the part that’s vibrating)? What is the tension in the...
Two different simple harmonic oscillators have the same natural frequency (f=1.70 Hz) when they are on the surface of the Earth. The first oscillator is a vertical spring and mass, the second is a pendulum. If both systems are moved to the surface of the moon (g=1.67 m/s2), what is the new frequency of the vertical spring and mass? Tries 0/20 Calculate the new frequency of the pendulum.
