how fast an object moves
speed
A wave in which the particles vibrate at right angles to the direction of wave
transverse
Part of the Em spectrum . Electromagnetic radiation
light
material that carries waves ; solid ,liquid and gas
medium
A disturbance that transfers energy from place to place
wave
A wave in which the particles move parallel to the path of the wave
longitudinal
waves caused by vibrations that are transmitted through matter. example of longitudinal
sound
maximum displacement from rest position ; shows the amount of energy
amplitude
the part of a longitudinal wave where the particles of the medium are close together
compression
highest point of a wave
crest
Lowest point of a wave
trough
the time it takes for one cycle
period
the part of longitudinal wave where the particles of the medium are far apart
rarefaction
a change in the direction of a wave when the wave finds an obstacles or an edge , such as an opening
diffraction
occurs when a wave bounces off a surface that it cannot pass through; upside down
reflection
a wave that require a medium to travel
mechanical
the distance between one crest or trough of a wave and next
wavelength
waves of energy traveling through rock
seismic
electromagnetic waves used for communication on computers , phones ,etc.
radio
the number of complete waves that pass a given point in a certain amount of time
frecuency
