The correct answer is The remote generates a systematic series of infrared pulses that signal a binary code. Key Points A remote uses light to carry signals from the remote to the device it controls. It emits pulses of invisible infrared light that correspond to specific binary codes. These codes represent commands, such as power on, volume up, or channel down. Remote controls work through sending electromagnetic waves through the air that the TV can pick up. The control sends out infrared waves which is a type of electromagnetic radiation just like Gamma rays, X rays etc. The first remote intended to control a television was developed by Zenith Radio Corporation in 1950. ​Nikola Tesla was the inventor of remote. A wireless remote control, the "Flashmatic," was developed in 1955 by Eugene Polley.
