Traveling Waves
A
°wave±
is a traveling disturbance that transports energy but
not matter.
Constructing Traveling Waves:
To construct a wave with shape
y = f(x)
at
time t = 0
traveling to the
right
with speed v
simply make the replacement
x
x
vt
→
−
.
Traveling Harmonic Waves:
Harmonic waves
have the
form
y = A sin(kx)
or
y = Acos(kx)
at time
t = 0
,
where
k
is the
"wave number"
(
k = 2
π
/
λ
where
λ
is the
"wave
length"
) and
A
is the
"amplitude"
.

harmonic wave traveling to the
right with speed
