Stellar Spectra Lab     

Phase I: Exploration:

Explore one relationship between temperature and spectra. Open this stellar temperature simulator:         http://astro.unl.edu/naap/blackbody/animations/blackbody.html

Click the box to label the peak wavelength. Use the slider bar to change the temperature.

Note the visible spectrum runs from about 400 nm (violet) to 700 nm (red).

1) Draw (or paste) the curve for 12,500 K    Draw (or paste) the curve for 5,000 K.

2) Look at the visible spectrum shown on the x-axis for wavelength.
