Household items using infrared radiation. These are a toaster,a remote control and an electric heater. Infrared is the portion of the electromagnetic spectrum with a longer wavelength that red light. It is felt as heat. This can be used to toast bread or warm a room. The remote control uses a rapidly pulsed beam of infrared radiation to control other electronic devices. The sensors block out ambient heat radiation and respond only to specific patterns of pulses from the control | |
