A fisher has anchored her 11 m long boat far away from the shore. The waves in the water cause the boat to rock, and the boat performs 12 vertical oscillations within 9 s. The wave crests travel from bow (front) to stern (back) of the boat in 3 s. She notes that at time t=0 the bow of the boat is at the top of a wave. She then observes the wave phase at bow again at t = 1 s What is the period of waves? T = | S What is the wavelength? λ = || What is the number of complete waves that fits in the length of the boat simultaneously? waves What is the angular velocity of the waves? w = m What is the wave phase at the time of the second observation [O0...2 pi]? rad
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.
