the room) and that is best done using the wave model. Rather, the sound waves of the radio cause longitudinal vibrations in the air in the entryway. The music from the radio can be audible directly in front of the entrance without diffraction. Diffraction occurs in all waves, not only sound waves. Your attempt to explain things in terms of the way the particles move is not valid - unless you consider all the particles in the region of the experiment (e.g. Diffraction is the term for the bending of a wave.

You can get exactly the same interference pattern with microwaves and ultrasound waves of the same wavelength (say 3cm) where the ratio between the frequencies is around 1000. The Neumann SBK 130 A sound diffraction sphere slips onto the KM 130, KM 131 (A/D) and KM 183 (A/D) pressure microphones. It isn't the frequency that counts - it's the wavelength and the result of the addition of all the possible paths between source and detector that produces nulls and peaks. The results of calculations of the pressure distribution on the surface of a stationary rigid sphere and a stationary rigid circular cylinder of infinite. I'm just really struggling to imagine how a faster vibrating molecule of air diffracts less than a slower vibrating one? So photons with a lower frequency will have a lower momentum a lower momentum will make it "easier" to deflect.īut it's such a crude way of thinking.maybe I'm clutching at straws lol :)

The only reason I can think of is a rather crude explanation by relating it to momentum of light (not sure how this would work for sound?) I'm still struggling as to why lower frequencies diffract more at a fundamental level. I understand that now (about the corner behaving as one side of an infinitely large gap).
