Propagating Waves

frequency ω
wavelength λ
reflection coefficient Γ
time
A sinusoidal incident wave, shown in black, impinges on a barrier at
x=0
. This results in a reflected wave (red) and a transmitted wave (blue), with relative amplitudes determined by a reflection coefficient
Γ
. You can also control the angular frequency
ω
and the wavelength
λ
with sliders. The propagation velocity of the wave is given by
c=ωλ/2π
.
