Radio wave propagation refers to the way radio waves travel through different environments. These waves can move through the air, water, and even solid materials, but their behavior changes based on factors like frequency, terrain, and atmospheric conditions. Understanding how radio waves propagate is essential for effective communication in technologies such as cell phones, radios, and satellite systems. Various factors influence radio wave propagation, including reflection, refraction, and diffraction. Reflection occurs when waves bounce off surfaces, while refraction happens when waves change direction as they pass through different mediums. Diffraction allows waves to bend around obstacles, enabling signals to reach areas that might otherwise be blocked.
