Infrared (UK: Infrared (IR)) is another name called infrared rays or radiation. Are electromagnetic waves with wavelengths between radio waves and optical frequencies in the range 10¹¹ - 10¹⁴ Hz frequency range with microwave. Red light has a wavelength between radio waves of all kinds of material at a temperature between -200 ° C to 4000 ° C will emit infrared out. Unique properties of infrared radiation as a deviation in the electromagnetic field. The difference is that the Based on the frequency properties The frequency is very high Energy was higher
