Have a look at http://www.falstad.com/mathphysics.html There's a whole
range of magnificent physics demonstrations done as Java 'applets'.
Enormous fun!.
Play with the '2D ripple tank' and use your mouse to add a couple of
walls and slots etc. It's then clear as to what happens to the
reflections when the frequency is taken up and down.
Seems to me that the long waves can't cleanly reflect, as they are
simple too diffuse wrt the obstacles. I.e they've gone round/slid along
the obstacle before the wave reverses.

Great link!
Thanks.
