Does a TV remote use electromagnets?
Remote controls work through sending electro magnetic waves through the air that the TV can pick up. The control sends out infrared wavesinfrared wavesBlack-and-white infrared negative films are sensitive to wavelengths in the 700 to 900 nm near infrared spectrum, and most also have a sensitivity to blue light wavelengths.https://en.wikipedia.org › wiki › Infrared_photographyInfrared photography - Wikipedia which is a type of electromagnetic radiation, which includes radio, gamma, and micro waves, as well as all visible light.
What is the difference between a smart remote and a regular remote?
