TV remote controls that rely on infrared radiation shootout pulses of IR energy from a light emitting diode (LED) to an IR receiver in the TV. The uses for UV light include a broad range of applications in commercial, industrial and healthcare settings. The type of applications that use UV lamps include the curing or drying of materials such as inks and coatings; disinfection for viruses and bacteria; hygiene and infection control; fluorescent inspection; and tanning. Microwaves are a form of electromagnetic radiation. They can cause water and fat molecules to vibrate so they are used for cooking in microwave ovens. They are used by mobile phones (produced from a transmitter chip and antenna) as well as WiFi. They are also used in radar, which is used by ships, aircraft and weather forecasters. One of the types of radar works by sending out bursts of microwaves and detect "echoes" coming back from objects that the microwaves have it and so can find the distance of the objects by detecting the time it takes for the "echo" to be received.
