Adding traveling waves - Superposition

Different Wave Configurations

Two identical waves (same amplitude and frequency)

Different Amplitudes, Same Frequencies

Same Amplitudes, Different Frequencies

Different Amplitudes, Different Frequencies

Same amplitudes and frequency - Different directions

Or, you can change the waves any way you want :

f(x,t) =

g(x,t) =
