Term | Definition |
---|---|
Wave | Disturbance that carries energy through matter or space. |
Medium | The matter through which the wave travels |
Mechcanical Wave | Waves that require the medium |
Electromagnetic Wave | Light waves |
Transverse Wave | Waves in which the particles are perpendicular to the motion |
Longitudial Wave | Waves that cause the particles in a medium to vibrate |
Crest | The highest point of transverse waves |
Trough | The lowestt points of transverse waves |
Amplitude | The greatest distance the particles are placed from eachother |
Wavelength | The distance from one crest to another |
Period | The time required for one full wavelength |
Frequency | The number of full wavelengths that pass a given point |
Doppler Effect | The motion of the force or observer |
Reflection | The bouncing back of a wave |
Diffraction | The bending of waves as they pass |
Refraction | The reason the waves bend |
Interference | A new wave that is different from the other waves |
Constructive interference | The sum of two indivdual waves formed by amplitudes |
Destructive Interference | When the crest of one wave meets the other |
Standing Wave | Can form when a wave is reflecting at the boundary of a medium |
