A flute can be modeled as an open-open tube. My flute is L = 0.5969 m from %3D mouthpiece (one open end) and the end (the other open end). Assume 20 °C. 3 mode when the flute is open to a) What is the frequency of the m = atmosphere only at the two open ends? b) I lift a key that creates a hole 2L/5 from the open end. Recall that this hole opens to atmospheric pressure, as do the open ends. i. Draw the lowest-frequency mode that meets the boundary conditions at the two open ends and this new hole at 2L/5. ii. Calculate the frequency and wavelength of this mode.
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.
