Electromagnetic Signals

Electromagnetic signals are waves of energy that transmit information through space without physical contact. They include visible light, radio waves, internet data, and more. These signals are generated by devices like antennas, microphones, or lasers, and they travel at the speed of light. When they reach a receiver, such as your smartphone or a TV, they are converted back into meaningful information like sound, images, or data. Electromagnetic signals are essential for modern communication, enabling wireless technology, broadcasting, and data transfer across distances.
