Sound Flashcards
what is sound
is a form of energy from vibrating objects
what kind of waves do sound has
longitudinal
what can sound travel through and can’t
can through: solids, liquids and gases
not through: a vacuum because there is no particals in a vacuum
how much does sound travel through air
340m/s which is slower than light
what is the frequency of a sound
number of vibration in a second
f=n/t
what happens when the wave has low and high frequency
low= the waves are far apart (higher wavelength)
high=the waves are more close together ( lower wavelength)
what is frequency measured in
hertz (Hz)
describe how loud sound waves look like
has a higher amplitude (bigger)
describe how quiet sound waves look like
has a lower amplitude (smaller)
what is the normal range of hearing
20-20000 Hz
