Animation for 2 wavelength for 1 period

animation for 2 wavelength,  green wave traverse to the right while blue wave transverse left, the net red wave amplitude at each point is the sum of the amplitudes of the individual waves

Amplitude modulation

amplitude modulation can be achieved through f(x,t) = 1.00*sin(2*pi/0.10*(x-1.00*t)) and g(x,t) = 1.00*sin(2*pi/0.11*(x-1.00*t))
only the resultant is visible to improve clarity of waveform

Inspire others to do good

Through my blog, I hope to inspire more people to help other people teach/learn better, even though we  have not meet them before.
