Hi all,
This is probably an error resulting from my qualitative understanding of diffraction, but in most basic descriptions of the phenomena they talk about diffraction occurring when light encounters an aperture that is equal to or smaller than the wavelength of the incident light with the relationship at its most basic being minimum resolvable separation distance of two objects = lambda/aperture diameter. Thats a very simple relationship to understand, however let's say the apertures I'm talking about are lenses and the light is emitted from the object plane not transmitted. The physical diameter of a lens is much greater than the wavelength of the light so why does diffraction still occur?
Many thanks
