Hi Dale,

I found (via Twitter I think) this video by Peter Evennett.  As a practical demonstration of resolution about half way through it is excellent, and may be easier to grasp for students than the purely dry physics theory.  Mind you, beware that it is using transmission rather than reflection, so the 2 NAs are not necessarily the same for the calculations, so this may confuse them further!

 about 20 mins in and further on.  Even demonstrates the difference with wavelength.  Really well done I think.

Otherwise, I'd '+1' Avi and Craig's answers.

Glyn.
