Unformatted text preview: More Radiation laws max = 0.0029/T meters where the temperature is in K and the resulting wavelength is in meters. The basic upshot of this formula is that when the temperature goes up, the wavelength where most of the light comes out at gets smaller (bluer). By using this formula it is possible to determine the temperatures of objects, or at least estimate them, so long as you can observe the peak for the energy output and you assume that the object is acting like a black body. Sometimes astronomers can do this, especially if the light comes out at a "normal" wavelength that we can detect. If you go back to the table listing all of the different types of light, the last column in the table refers to the temperature range needed to produce that type of light. I should mention that the energy outputs of objects are quite diverse. The curves shown in Figure 9 indicate that energy is given out at many wavelengths, not just at the peak wavelength. If you can't see the energy at the peak wavelength due to a lack of the proper equipment, it is probably...
