Wave Parts
The length of one wave
Wavelength
When a wave bounces off of a surface or new medium
Reflection
The speed of sound in air at normal temperature and pressure
330 m/s
This is the opening of the ear that sounds first enter
Ear canal
Sound that is recorded by converting sound waves into electronic signals that can be processes and stored.
Sound Reproduction
The height of a wave
Crest
When a wave changes speed and bends
Refraction
The speed of sound in a solid
Fastest
The is the transparent membrane that takes vibrations and transfers them to the hammer
Ear drum
The shorter the length the higher the frequency
The relationship between length and frequency in a musical instrument
The low point of a wave
trough
When a wave bends around an obstacle or through a small opening
Diffraction
The speed of sound in a gas
Slowest
This is the last of the small bones in the ear that takes vibrations from the anvil
Stirrup
When two waves interfere to make a bigger wave
Constructive interference
A wave that vibrates the particles of the medium perpendicular to the direction of the wave
Transverse
When two or more waves occupy the same space at the same time
Interference
When sound bounces off of wall or building and returns to our ears
Echo
This is the part of the ear fill with fluid that takes vibrations from the stirrup
Cochlea
What all waves carry
Energy
A wave that vibrates the particles of the medium parallel to the direction of the wave
Longitudinal
When two or more waves interfere to make a wave that appears to stand still
Standing wave
The speed of sound if it covers 2200 m in 1.42 seconds in salt water.
1546 m/s
This is the part of the ear that transfers vibrations to the brain in the form of electricity
Auditory nerve
The period of a wave that has a frequency of 2 Hz
0.5 seconds
