A visualization and associated activity to explain how Planck’s Law can be used to plot blackbody curves of objects with different temperatures, the relationship between temperature and peak wavelengths in the electromagnetic spectrum, and the greenhouse effect of Earth’s atmosphere.

Use this tool to help students find answers to:

  1. How can Planck’s Law be used to plot blackbody curves of objects at different temperatures?
  2. What is the relationship between temperature and peak wavelengths in the electromagnetic spectrum?
  3. Why does the surface temperature of Earth increase due to the greenhouse effect of the Earth’s atmosphere?
