Infared Radiation

Infrared radiation

Infrared radiation is commonly referred to as heat radiation. The wavelength of infrared radiation is slightly longer than that of visible light. The wavelength is between 1 mm and 0.00007 mm. All objects radiate heat radiation. Objects send out more heat radiation as they get warmer. Therefore, hot objects send out more energy than cold ones. Heat radiation is also a factor that could lead to global warming, seeing as the earth also sends out heat waves.

Infrared radiation has many uses. Common uses include night vision, meteorology and thermography.
