So I heard that diffraction through an opening is most pronounced when the wave encounters an obstacle or a slit that is comparable or smaller in size to its wavelength.
But I also heard that if the slit is smaller than the wavelength, then wavelength cannot pass through the slits anymore and diffraction will be less pronounced/will not happen.
So these two contradictory statements are confusing me. Which one is right, or am I missing some sort of big picture here?
