INFRARED RADIATION CAN BE USED TO MONITOR TEMPERATURE

infrared radiation (ir) is also known as heat radiation. it's given out by all hot objects - and the hotter the object, the more ir radiation it gives out

this means infrared can be used to monitor temperatures. for example, heat loss through a house's uninsulated roof can be detected using infrared sensors

infrared is also detected by night-vision equipment. the equipment tuns it into an electrical signal, which is displayed on a screen as a picture. the hotter an object is, the brighter it appears…
