a type of wave in which the disturbance moves at right angles, or perpendicular, to the direction in which the wave travels
Transverse Wave
a disturbance that transfers energy form one place to another without requiring matter to move the entire distance
Wave
the maximum distance that a disturbance causes a medium to move from its rest position; the distance between a crest or trough of a wave and line through the center of a wave
Amplitude
the number of waves that pass a fixed point in a given amount of time, usually one second; the number of cycles per unit time
Frequency
the highest point, or peak, of a wave
Crest
the lowest point, or valley, of a wave
Trough
a substance through which a wave moves
Medium
the bending of a wave as it crosses the boundary between two mediums at an angle other than 90 degrees
Refraction
the bouncing back of a wave after it strikes a barrier
Reflection
the spreading out of waves as they pass through an opening or around the edges of an obstacle
Diffraction
the part of the electromagnetic spectrum that consists of waves with frequencies higher than those of visible light and lower than those of x-rays
Ultraviolet light
a type of wave in which the disturbance moves in the same direction that the wave travels
Longitudinal Wave
a wave, such as a sound wave or a seismic wave, that transfers kinetic energy through matter
Mechanical Wave
equal to the distance between the trough and the equilibrium position.
