Which phenomenon is illustrated by RF bending around an object?

The phenomenon illustrated by RF (Radio Frequency) bending around an object is diffraction. This occurs when a wave encounters an obstacle or aperture that is comparable in size to its wavelength. As the wave front interacts with the edge of the object, it bends and spreads out, creating a pattern of waves behind the object that can be detected even in areas where the waves would not normally propagate without this interaction.

Diffraction is especially relevant in applications involving RF and sound waves, as it affects how signals propagate in various environments, such as urban areas with buildings or natural landscapes. Understanding diffraction is crucial for optimizing antenna placement, improving communication systems, and enhancing radar technology, where the ability for waves to bend around obstacles can significantly impact signal reception and clarity.
