|
Transverse wave |
wave vibrating at right angles to the direction of its propagation. |
|
|
Compression wave |
they produce compression and rarefaction when traveling through a medium, and pressure waves, |
|
|
Crest |
A crest is the highest point the medium rises to and a trough is the lowest point the medium |
|
|
Trough |
A trough is the opposite of a crest, so the minimum or lowest point in a cycle. |
|
|
Compression |
A compression is a region in a longitudinal wave where the particles are closest together. |
|
|
Rarefaction |
Rarefaction is the reduction of an item's density, the opposite of compression. |
|
|
Frequency |
frequency is the hertz (Hz), corresponding to one crest per second. |
|
|
Amplitude |
the maximum displacement or distance moved by a point on a vibrating body or wave |
|
|
Wavelength |
the distance between successive crests of a wave, especially points in a sound wave |
|
|
Medium |
is any substance that carries the wave, or through which the wave travels. |
|
|
Electromagnetic wave |
one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field |
|
|
Mechanical wave |
an oscillation of matter, and therefore transfers energy through a medium |
|
|
Pitch |
used to describe how high or low a note a being played by a musical instrument or sung seems to be |
|
|
Refraction |
change in direction of a wave passing from one medium to another caused by its change in speed. |
|
|
Absorption |
electromagnetic radiation is the way in which the energy of a photon is taken up by matter, |
|
|
Reflection |
Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium |
|
|
Doppler Effect |
an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. |
