High diffraction occurs due to which type of wavelength?

High diffraction is associated with long wavelengths, which correspond to low-frequency sounds. This phenomenon occurs because longer wavelengths can bend around obstacles and travel through openings more effectively than shorter wavelengths.

In acoustics, when a sound wave encounters an obstacle or an aperture that is comparable in size to its wavelength, it tends to spread out. Longer wavelengths create low-frequency sounds, which can easily navigate around these obstacles, resulting in pronounced diffraction effects. This property of sound waves is particularly important in applications where sound needs to be delivered in specific patterns or directions, such as in hearing aid design and acoustic engineering.

In contrast, short wavelengths, or high-frequency sounds, exhibit reduced diffraction, meaning they tend to travel in straight lines and are less affected by obstacles, which is why they may not diffract as much as lower frequency sounds.
