SUMMARY
Diffraction plays a critical role in signal interference, particularly affecting electromagnetic (e/m) waves. It can be both beneficial and detrimental; while it allows for wave propagation along the Earth's surface, it can also lead to destructive interference. Specifically, when two radio waves of the same frequency are 180° out of phase, they can cancel each other out, resulting in a null signal at certain locations. Additionally, diffraction patterns can be observed in visible light, producing alternating bright and dark lines or concentric rings from linear or circular diffraction gratings.
