TermDefinition
Sound wave wave is a mechanical wave because it has to travel through a medium. It is also a compression wave.
Medium is the substance through which a wave can travel
Reflection occurs when a wave strikes an object or surface and bounces off
Refraction is the bending of a wave as it moves from one medium into another
Sound vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ea
Medium A substance that makes possible the transfer of energy from one location to another, especially through waves
Pitch The sensation of a frequency
Amplitude the maximum extent of a vibration or oscillation, measured from the position of equilibrium
frequency the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second
mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium
