This is it, time to test what you have learned and see if you
can put it all together.
Traveling Waves
The standard equation of a wave in motion is
y(x,t) = A sin (K x + O t + P)
where A is the wave amplitude, K is the wave number (2*pi/wavelength),
O is the angular frequency omega (2*pi*frequency), and P is the phase in radians.
Write an applet that shows a picture of a traveling wave over time, letting the
user adjust the wavelength and the frequency.
