Standing Waves: Amplitude, Nodes, and Energy

[Abhishekdas]

Standing waves...

Homework Statement

If two waves differ only in amplitude and are propagated in opposite directions through a medium, will they produce standing waves. Is energy transported?

Homework Equations

The Attempt at a Solution

About the first part i think they do produce standing waves in which there are no nodes but there are maximum and minimum values of amplitude...I don't know if this is exactly a standing wave and is energy transported?

Any help here?

No, they will not produce standing waves if the amplitudes are different. Take a look at this http://faculty.uml.edu/cbaird/95.658(2011)/Standing_Wave.zip" I wrote.
