Diffraction of RF - how is it affected by frequency?

[QUOTE="sophiecentaur, post: 6646114, member: 199289"] The simplest example of diffraction is the diffraction by two very thin sources. The [URL='http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/slits.html']Young's Slits experiment[/URL] is usually the first approach to diffraction; when there are two or more very small sources, the term 'interference' is used. (I chose this link because it's much more basic and uncluttered than the Wiki pages) Cancellation and enhancement of the waves from the two slits depends on the relative phases of the waves (the path difference). The formula shows that a half wavelength path difference is greater as the wavelength decreases and so the angle for cancellation must be smaller. (That's your "logical" argument in a nutshell). Diffraction, in general, is the result of an infinite number of contributions over a source of finite width but it's only a step further in the same direction as for interference from just two sources.
