waves Flashcards
what state of matter does sound travel quickest
solids
transverse wave
light
longitudinal
sound
distance from center to top of the wave is
amplitude
pitch of the sound depends on
frequency
how do we ditect vibrations and turn them into electrical
microphone and oscilloscope
wave calculations
wave speed (m/s)= frequency (hertz) x wavelength (m)
how can hearing be damaged
ear wax
loud noises
objects
howavoid ear damage
ear defenders
ear plugs
avoiding loud sodidbd
outside of ear
pinna
opening of ear
auditory canal
third part of era
eardrum
snail thing
ossicle s
other to kmg
auditory nerve
auditory nerve
passes electrical signal to the brain
cochlea
to make an electrical signal when the liquid and tiny hairs move
ear drum
it vibrates when a sound wave hits it and passes the vibration to the ossicles
pinna
to guide sound waves to the ear
auditory canal
guide wave to ear drum
ossicles
to amplify the sound vibration and pass it to cochlea
an echo is
a reflection of sound
what type of energy is the wave transferring
kinetic
frequency
number of waves per second
echo is
reflection of a sound wave y an object
