An Interactive Blackbody Spectrum Plotter is a digital learning tool that simulates how an idealized object (a blackbody) absorbs and emits thermal radiation across different wavelengths and temperatures. These online applets—such as the widely used PhET Blackbody Spectrum Simulation by UC Boulder—provide a crucial visual bridge for understanding the birth of quantum mechanics.

As users interact with the plotter (usually by dragging a temperature slider), the application automatically updates a live spectral graph to demonstrate three foundational laws of physics:
