Explain the difference between a high pitched sound and a low pitched sound based onwhat you have learned about sound and its properties. ille do porWaves are defined as rhythmic disturbances that carry energy without carrying matter. As awave travels, the energy moves from one point to another. The matter through which thewave travels, known as a medium, vibrates but does not drastically change position.Imagine a stadium full of people doing (you guessed it!) the wave. Each person stands up asthe wave passes, but they don't leave their area. This is also how sound waves pass throughmaterials. Each particle vibrates as the energy of the wave passes through it, but it eventuallyreturns to its resting point.Waves that require a medium to travel are known as mechanical waves. Light is not amechanical wave because it can travel through empty space. Sound, on the other hand, is amechanical wave because it cannot exist without a material to travel through. Usually,sound's medium is air. As the energy of sound passes through the air, the molecules itpasses through are disturbed and vibrate left and right.Mechanical sometimes create disturbances that cause particles to vibrate up and down.These are known as a transverse waves. Other times, the particles that are disturbedvibrate left and right, creating a compression or longitudinal wave. Sound is acompression wave.longitudinal wavetransverse waveTo better illustrate the differences between these two waves, imagine a slinky stretched outbetween two students. If one student wiggles the slinky up and down, a transverse wave iscreated. On the other hand, if one student pushes the slinky in the same direction that it isstretched, a wave of compressed springs will travel along the slinky until it reaches the otherside. This is the way that a sound wave behaves.Sound is created when air particles are compressed by a speaker, vocal cord, or any othervibrating object. The air particles closest to the disturbance will move slightly in the directionaway from the vibrating material before returning to their original location. When the particlesare displaced, they press up against more air particles, which will vibrate away in response aswell. This creates a domino effect in which the vibrating energy travels outward from thesource, just like the compressed slinky in the example above.©Laney Lee 2021R 72716KAZILHECHO EN BRAco04089Walm

Many of the topics discussed in this chapter are useful beyond the topics of mechanical waves. It is hard to conceive of a mechanical wave with sharp corners, but you could encounter such a wave form in your digital electronics class, as shown below. This could be a signal from a device known as an analog to digital converter, in which a continuous voltage signal is converted into a discrete signal or a digital recording of sound. What is the result of the superposition of the two signals?
