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 |
