Waves
Term | Definition |
---|---|
Wave | A repeating disturbance transferring energy |
Medium | Any material a wave travels through |
Transverse Wave | A wave that displaces material at right angles to the wave's direction |
Compressional Wave | A wave that that displaces material in line with the wave's direction |
Mechanical Wave | A wave that requires matter to travel |
Crest | The high point of a transverse wave |
Trough | The low point of a transverse wave |
Rarefaction | The less dense region of a compressional wave |
Compression | The high density region of a compressional wave |
Wavelength | The distance between two identical points in adjacent waves |
Frequency | The number of waves that pass a point in a second (waves/time) |
Period | The time it takes for one wavelength to pass a point (time/wave) |
Amplitude | A way of measuring the energy carried by a wave |
Reflection | The bouncing of a wave off a surface |
Refraction | The bending of a wave as its speed changes moving from one medium to another |
Diffraction | The change in direction of a wave as it bends around an object |
Interference | Two or more waves overlap and form a new wave |
Absorption | The energy of a wave is transferred into a material |
