Electromagnetic waves play a crucial role in wireless communications by transmitting information through the air without the need for physical connections. These waves, which include radio, microwave, and infrared frequencies, carry data encoded in various forms, such as amplitude or frequency modulation. Wireless technologies, such as Wi-Fi, cellular networks, and satellite communications, utilize these electromagnetic waves to enable devices to communicate over long distances. The ability to modulate and demodulate these waves allows for efficient and reliable data transfer in a variety of applications.
