Answer:
The common TV remote control uses (3) infrared waves.
Explanation:
Infrared waves: An electromagnetic wave is an infrared wave. The finder was William Herschel. Due to their longer wavelengths than visible light, infrared waves can travel across crowded areas of gas and dust in space without being significantly scattered or absorbed. The electromagnetic radiation we refer to as "infrared" has a certain wavelength or colour. They range in size from 700 nanometers to one millimetre. Keep in mind that 1 mm equates to 1,000,000 nanometers. On the red side of the rainbow, they are just barely beyond what human eyes can see.
The typical TV remote uses infrared wavelengths to communicate.
