Question 25 In an experiment, two students measured the speed of sound in sea water at room temperature (20°C). Both of the students recorded their results in their notebooks as follows: A) (1515 + 7)m/s B) (1522 + 4) m/s The students then looked up the value for the speed of sound in sea water and found it to be 1531 m/s. Which of the following statements best describes the comparison between the students' results and the accepted value for the speed? The values that the two students found did not agree with each other, but one of the student's answer did agree with the accepted value. The values that the two students found agree with each other but not with the accepted value. The values that the two students found did not agree with each other, nor with the accepted value. The values that the two students found agree with each other and with the accepted value. The values that the two students found were wrong and should have agreed with the accepted value.

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.
