1. Mac and Tosh are resting on top of the water near the end of the pool when Mac creates a surface wave. The wave travels the length of the pool and back in 25 seconds. The pool is 2 583 cm long. Determine the speed of the wave.
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.
Is the formula to be used is v=s/t? If so the answer is 2.07 m/s. However, my teacher told me to use the wavespeed formula that lamda= 2583 cm and frequency is 0.04 Hz. However I think that is wrong. I asked her why lamda is 2583 if it clearly states that the 2583 is the length of the pool not the wave itself. She told me that wavelength and distance is the same. But still I rejected. Is wavelength and distance the same? If not how are they different
