Lucy has three sources of sound that produce pure tones with wavelengths of 60 cm, 100 cm, and 124 cm. She also has an assortment of narrow tubes that are closed off at one end but open at the other. After experimenting, Lucy notices that each tone will resonate with tubes of some lengths but not with others. For each wavelength, determine which tube lengths, if any, will resonate with sound of that wavelength. Wavelength of sound: 60 cm 100 cm 124 cm Length of tube: Answer Bank 15 cm 25 cm 45 сm 30 cm 75 сm 93 сm
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.
