wave

a disturbance that transmits energy through matter or space

medium

a substance through which a wave travels

mechanical wave

a wave that REQUIRES A MEDIUM which to travel

electromagnetic wave

a wave that DOES NOT REQUIRE A MEDIUM through which to travel

wave length

distance between two successive identical parts of a wave

amplitude

the height of a transverse wave; proportional to the energy of the wave

transverse wave

a wave in which the medium moves perpendicular to the direction the wave travels....... all electromagnetic waves; some seismic waves; "the wave"

longitudinal

a wave in which the medium moves parallel to the direction the wave moves..... sound, some seismic waves

compression

part of a longitudinal wave where the medium is PACKED TOGETHER

rarefaction

part of a longitudinal wave where the medium is spread apart

surface wave (water wave)

causes the medium to move in a circular pattern...happens at the surface between two media

period

the amount of time for one complete wave to pass by a point

frequency

# of waves that pass by a poing in one second

reflection

the bouncing of a wave as it makes a surface between two media

refraction

the bending of a wave as it passes from one medium to another at an angle ofther 90 degrees
