Part A Several different incandescent radiation sources are listed in the table below, along with their respective temperatures. Sunlight
is provided as a baseline measurement at the top of the table. You will determine the peak Intensity for each source with
respect to its visible color spectrum. You also estimate the amount of emitted energy that falls in the visible light spectrum
To do so
• drag the slider to reach the temperature listed in the first column of the table. You can also type in the temperature value
In the text box above the temperature slider.
• use the buttons to zoom in or out on either the vertical or horizontal axis to easily observe the curve (and the peak). The
peak should be as high as possible, while still being visible on screen. You should extend the scale far enough to the right
to see the curve reach very close to zero emission on the right.
• estimate the percentage of emitted energy that appears to fall within the visible spectrum and enter that value in the
table. You can do this by estimating the area under the energy curve in the visible region as compared to the total area
under the curve.
