Radio transmission
Radio transmission involves sending information through electromagnetic waves over distances. A transmitter converts audio or data signals into these waves, which travel through the air. A receiver then captures these waves and converts them back into the original audio or data. This technology allows for communication across various mediums, like radio broadcasts, cell phones, and Wi-Fi. Radio waves, which are part of the electromagnetic spectrum, can vary in frequency and wavelength, determining their range and application. Generally, lower frequencies travel farther, while higher frequencies carry more data but have shorter ranges.

Radio transmission is the process of sending information, such as voice or music, through the air using radio waves. These waves are a type of electromagnetic radiation that travel at the speed of light. A transmitter converts audio signals into radio waves, which are then broadcasted via an antenna. A receiver picks up these waves using another antenna and converts them back into sound. This technology allows for wireless communication over varying distances, making it fundamental for radio broadcasting, television, and mobile communications.
