A very short sound pulse is generated at the open end of a 2.00 m long gas-filled tube, which is closed at the other end. The emperature of the gas is 273 K. The echo is heard after 0.010 s. Is the speed of sound in the gas faster or slower than in air (at he same temperature). Select one: O A. Impossible to calculate because the speed of sound in the gas is not known. O B. Neither, since the speed of sound is a constant. O C. Speed is slower in the gas than in air. O D. Speed is faster in the gas than in air.
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.
