If the wavelength of a wave is smaller than the dimensions of the obstacle it faces, it will get reflected by the obstacle. Waves of shorter wavelength spread out (diffract) less after passing through the slits, and the short wavelength leads to a smaller angle at which constructive interference (one wavelength path difference between the two waves) will occur. The reason has to do with what's stopping the sound. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium.

High frequency waves have a shorter wavelength because they are compressed more tightly together. "like 500nm, which can be similar to the size of air molecules.". High frequencies are better reflected whereas low frequencies are able to pass through the barrier: This is and frequency-based attenuation are why low-frequency sounds are much easier to hear through walls than high frequency ones. Why are radio signals more clear at night? In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. High frequency radio signals have a shorter range due to the shorter wavelength.
