what is a wave’s amplitude?
maximum
displacement
of a
point
on a wave from its
undisturbed
position
what is a wavelength?
distance
from a point on a
wave
to the
same
position on the
adjacent
wave
most commonly
peak
to
peak
or
trough
to
trough
what is the frequency of a wave?
number of
waves
that pass a
given point each second
unit used for frequency
Hertz,
Hz
what is meant by a frequency of 200Hz?
200
waves pass a
given point each second
what is wave speed?
speed at which the wave
moves
or at which
energy
is
transferred
through a
medium
what does a wave transfer?
energy
equation used to calculate wave speed
wave speed =
frequency
x
wavelength
speed (
m/s
),
frequency
(
Hz
),
wavelength
(
m
)
The speed of a wave depends upon its
frequency
and
wavelength.
The
higher
the
frequency,
the
shorter
the
wavelength
and vice versa.
