What occurs with small frequency in terms of wave behavior?

When considering wave behavior, lower frequency waves are associated with longer wavelengths. Diffraction is the bending of waves around obstacles and through openings, and its extent is influenced by the wavelength of the wave in relation to the size of the obstacle or slit.

A longer wavelength allows for greater bending, resulting in more pronounced diffraction. Therefore, when the frequency is small, the wavelength is large, leading to increased diffraction effects. Conversely, a small frequency means less diffraction because the diffraction effect tends to be minimal for smaller wavelengths relative to the size of openings and barriers.

In summary, smaller frequencies correspond to less diffraction because the associated longer wavelengths tend to produce more noticeable diffraction patterns, especially when interacting with obstacles or slits that are comparable in size.
