SI Session 2 Define Period (T): Frequency (f): A buoy bobs up and back down in 2.4 seconds. The buoy makes it 0.2 meters away in 7 seconds. What is the period? What is the frequency? What is the velocity? What is the wavelength? What is the difference between longitudinal and transverse waves? Circle the correct answer. Light is a transverse / longitudinal wave. Sound is a transverse / longitudinal wave. The wave below is traveling at 3 m/s. What are both the space and time functions of the wave below?
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.
