a. What part of the EM spectrum would be useful to determine the surface temperature of objects such as asteroids? Explain your answer. Infrared b. The surface of Mars appears reddish. Is Mars ‘red-hot’? If so, what is its surface temperature? If not, where is the red light coming from?
Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education <a {{0}}>research</a> and engage students through an intuitive, game-like environment where students learn through exploration and discovery.
In this lab you will use an incandescent light bulb and a prism spectrometer to measure the blackbody spectrum. Although a light bulb is not a blackbody (it emits much more radiation than it absorb!) it is a good approximation of a grey body: an object that emits a fraction of the blackbody spectrum with the same frequency distribution.

29 Μαΐ 2024 · Blackbody radiation was one of the first experiments that lead to quantum mechanics. It started with the simple observation that when you heat a metal that it first becomes red, followed by yellow and then white hot as the temperature increases.
The radiation represents a conversion of a body’s thermal energy into electromagnetic energy, and is therefore called thermal radiation. Conversely all matter absorbs electromagnetic radiation to some degree. An object that absorbs all radiation falling on it at all wavelengths is called a blackbody.
