Can the temperature of an object be derived from the EM Wave

[QUOTE="Drakkith, post: 5469324, member: 272035"] You can indeed measure the temperature by measuring the emitted spectrum of EM radiation from the object. Note that all objects emit a broad range of frequencies, with the peak frequency (frequency with the largest proportion of energy) increasing as the temperature of the object increases. [URL='http://www.spectralcalc.com/blackbody_calculator/blackbody.php']Here's a calculator[/URL] you can play around with to see how the emitted wavelength and frequency reacts to changes in temperature. You'd also need something capable of measuring the radiation. For a room temperature object, the emitted radiation falls mostly in the long-wavelength infrared region, so you'd need a sensor capable of seeing that. [/QUOTE]
