Yes that sounds right. The change in wavelength dependence comes from the propagation constant (the argument in the exponential) so the peaks in this exponential are spaced differently than in freespace. The propagation constant changes i

To be precise, 1/4 guide wavelength which is different than the freespace wavelength and depends on the diameter of the can. Here is a calculator that can spit out the guide wavelength http://www.turnpoint.net/wireless/cantennahowto.html
