In this lab you will be looking at the nature of the radiant energy that is emitted from an object based on its temperature. To change to a different temperature star, click on the star.

You will be seeing light in the visible as well as near ultraviolet and near infrared range.

Make sure you observe each temperature star for at least 30 seconds to get a sense of the relative amount of light emitted at different wavelengths.
