Waves pass through a 10.-centimeter opening in a barrierr without being diffracted. This observation provides evidence that the wavelength of the waves is much shorter than 10. cm. This is a multiple-choice question, and this is not the question that I am asking. I want to use this as an example to ask that why wavelength matters in diffraction, like in slit problem. If the wavelength is long, then what happens? If it is short, then?
thanks.
thanks.
