Waves of which their particles travel parallel to the direction of energy flow
1 of 22
Tranverse waves
waves in which their particles travel perpendicular to the energy flow
2 of 22
Loudspeakers
they work by converting electrical energy to kinetic energy. The wave hits a flexible plate called the diaphragm which vibrates like the eardrum and produces an electric signal like the cochlea.
3 of 22
reflection
a sound wavereflects of a surface we hear an eacho. Hard and smooth surfaces are good at reflecting whereas soft and rough surfaces absorb the wave.
4 of 22
oscilloscope trace
wave pattern seen upon the oscilloscope
5 of 22
amplifier
makes a sound louder
6 of 22
loudnesss and pitch
larger the amplitude the louder the sound. Higher the frequency the higher pitch the wave has. A short wavelength gives a high frequency.
7 of 22
trough
minimum point of a wave
8 of 22
crest
maximum point of a wave
9 of 22
amplitude
distance between the center to the to the trough/crest
10 of 22
pitch
how quickly the wave makes the air vibrate
11 of 22
frequency
the number of waves passing a point at a time
12 of 22
compression
when molecules are forced
13 of 22
rarefaction
when molecules are given extra space
14 of 22
quality
sounds with the same pitch and loudness
15 of 22
superpose
when waves pass through the same medium at the same time time they pass through each other without getting disturbed
16 of 22
ear drum
a tight sheet of skin which vibrates when sound hits it
17 of 22
ear canal
a tube in which sound is carried from the pinna to the ear drum
18 of 22
auditory nerve
sends nerve messages to the brain
19 of 22
ear bones
pass on vibrations from the ear drum to the cochlea
20 of 22
cochlea
contains sense cells that detect vibrations
21 of 22
sense cells
are very delicate cells in the cochlea. If they are damaged they can lead the person to become partially deaf.
