2 All waves have common properties such as:
amplitude, wavelegth, frequency, and
speed.
2.1 Amplitude
2.1.1 Is the maximum
distance the
midium vibrates
from the rest
position.
2.1.1.1 The hight of wave's
crest depends on its
amplitude.
2.2 Wavelength
2.2.1 The distance between two
corresponding parts of a
wave.
2.2.1.1 You can find the
wavelength of a
transverse wave by
measuring the
distance from crest
to crest.
2.3 Frequency
2.3.1 Is the numer of waves that
pass a point in certain mount
of time.
2.3.1.1 Frequency is measured in units
called hertz (Hz), and it is defined
as the number of waves per
second.
2.3.1.1.1 For example, a wave that occurs every
second has a frequency of 1 wave per
second (1/s) or 1 Hz. If two waves pass
every second the frequency is 2 waves per
second (2/s) or 2 Hz.
2.4 Speed
2.4.1 The speed of a wave is how far the wave
travels in given mount of time.
2.4.1.1 You can determine wave's speed
by diving the distance it travels by
the time it takes to travel that
distances.
2.4.1.1.1 As long s the temperature
of the midium (air) doesn't
change, the speed sound
will stay the same.
