ABSTRACT
This chapter describes the waves in general, and focuses on sound waves in particular. Common types of waves are water, light, sound, and radio waves. Creating waves on water requires disturbing the water. For example, tapping the water with a stick at some rate or frequency will produce a wave with the same frequency. Multiple waves can travel through the same medium without affecting each other. The overall wave will be the sum of all the waves. Multiple waveforms, acting together, make up the tone of a sound. The waves making up one sound may have different frequencies, phases, and intensities. The resonance frequency is the frequency at which if a system is stimulated with will produce a maximum response. Sound is a longitudinal wave. Sound waves need a medium through which to travel, such as air, solids, or liquids.
