Theory of Knowledge Connections
Wavefronts and rays are visualizations that help our understanding of reality, characteristic of modeling in the physical sciences. How does the methodology used in the natural sciences differ from the methodology used in human sciences? How does the scientific community decide between competing theories?
Nature of Science
Scientists have discovered common features of wave motion through careful observations of the natural world, looking for patterns, trends and discrepancies and asking further questions based on these findings.
The conflicting work of Huygens and Newton on their theories of light and the related debate Fresnel, Arago and Poisson are demonstrations of two theories that were valid yet flawed and incomplete. This is an historic example of the progress of science that led to the acceptance of the duality of the nature of light.
