Which of the following statements are TRUE of the harmonics and standing wave patterns in guitar strings? Identify all that apply. The fundamental frequency of a guitar string is the highest frequency at which the string vibrates. The fundamental frequency of a guitar string corresponds to the standing wave pattern in which there is a complete wavelength within the length of the string. The wavelength for the fundamental frequency of a guitar string is 2.0 m. The wavelength for the second harmonic played by a guitar string is two times the wavelength of the first harmonic. The standing wave pattern for the fundamental played by a guitar string is characterized by the pattern with the longest possible wavelength. If the fundamental frequency of a guitar string is 200 Hz, then the frequency of the second harmonic is 400 Hz. If the frequency of the fifth harmonic of a guitar string is 1200 Hz, then the fundamental frequency of the same string is 6000 Hz. As the frequency of a standing wave pattern is tripled, its wavelength is tripled. If the speed of sound in a guitar string is 300 m/s and the length of the string is 0.60 m, then the fundamental frequency will be 180 Hz. As the tension of a guitar string is increased, the fundamental frequency produced by that string is decreased. As the tension of a guitar string is increased by a factor of 2, the fundamental frequency produced by that string is decreased by a factor of 2. As the linear density of a guitar string is increased, the fundamental frequency produced by the string is decreased. As the linear density of a guitar string is increased by a factor 4, the fundamental frequency produced by the string is decreased by a factor of 2.
Properties of sound
A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).
Quality Of Sound
A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vibrate about a certain average position and create compressions and rarefactions. This is called pitch which is defined as the frequency of sound. The frequency is defined as the number of oscillations in pressure per second.
Categories of Sound Wave
People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules that travel further. Both of them describe it as vibration generated by an object, the difference is one talks about how it is received and other deals with how it travels and propagates across various mediums.
