Wave
A disturbance that transfers energy from place to plae
Energy
The ability to do work or cause change, such as moving an object some distance.
Medium
materiel through witch wave travels
Mechanical wave
A wave that requires a medium though witch to travel
transverse wave
A wave that moves the medium in a direction perpendicular to the direction in witch the wave travels
Congression
the part of the longitudinal wave were the particles of the medium are close together
Crest/trough
Trough:The lowest part of the wave
Crest: Highest part of the wave
longitude wave/compressinal wave
A wave that moves the medium parallel to the direction in which the wave travels
reflection
The bouncing back of a wave when it hits a surface though which it can not pass
Diffraction
The bending of waves around a barrier
Node
A point 0 amplitude on a standing wave
rest position
The position that the wave would be if it had no energy
Amplitude
The maximum distance that the particles of a medium move away from their rest positions as a wave passes through the medium
frequiency
the number of complete waves that pass a given point in a certain amount of time
hertz (HZ)
Unit of measurement for frequency
intensity
the amount of energy per second carried though a unit by a wave
Decibels(DB)
A unit of measurement of loudness
Parts of the ear
Pinna,Ear canal,Ear drum,Middle ear, inner ear
Doppler effect
the apparent change in frequency of a sound as the source moves in relation to a listener
Factors that effect the speed of sound
The speed of the sound depends on the density and the elasticity of the medium through which it travels.
