WebWell, changing the wavelength is equivalent to changing the size of the slit. If we make the slit bigger, and make the wavelength bigger by the same amount, then the difference in distance between the sources is greater, but the rate of change in the wave function is slower, so the phase difference between the two extremes of the slit is the same. Web1. A wave is a perturbation in a system that propagates. The wavelength is the typical length along which a wave is coherent, which means that what happens at some position affects …

http://hyperphysics.phy-astr.gsu.edu/hbase/Sound/diffrac.html WebLower frequency waves travel further as surface waves. They tend to follow the earth's curvature due diffraction and attenuation. Diffraction causes bending and is inversely proportional to the wave's frequency. Attenuation, along with energy loss, also makes the waveform to tilt downwards. This essentially helps in following the earth's curvature.

WebWaves can spread in a rather unusual way when they reach the edge of an object – this is called diffraction. The amount of diffraction (spreading or bending of the wave) depends on the wavelength and the size of the … WebHigh 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.
