Having trouble drawing the wave representations for this diagram.(adsbygoogle = window.adsbygoogle || []).push({});

[PLAIN]http://img156.imageshack.us/img156/94/diag.png [Broken]

I'm not sure what the incident and reflected waves should look like.

The question is asking to draw the waves in each region. I understand how to calculate the waves just not how to represent them.

Any help appreciated thanks.

EDIT: I also understand that the wavelength must be smaller in the middle. What I'm unsure of is where exactly to draw the reflected waves.
