In the Summer Olympic games, the Korean athlete won the single match for the Archery played by Park Seo-joon against the Japanese athlete. During the last round, Park Seo-joon stretched his arm while dragging his arrow at the bow and shot the target board at yellow points. When Park Seo-joon reloaded his last bow, it made a velocity of 70 m/s and heard its sound after 2 seconds 1) What is the exact time (s) in which Park Seo-joon released his bow and hit the target board when the bow had a sound velocity of 30 m/s 2) What is the distance (m) of the target board from where Park Seo-joon positioned and held his bow?
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.
