Revealing the Nature of the Final Image in Newton's Experimentum Crucis (2015)

unapi

In his crucial prism experiment, Newton noted the position of the final image, but not its shape or coloring. Most scholars describe the image as a single-colored representation of the selective aperture; some report multiple colors. When the experiment is re-enacted as the transformation of a camera obscura image, it becomes clear that the final image is a rainbow-colored representation of the outside world. Backward ray tracing enhances Newton's demonstration of diverse refrangibility. Using a projector, teachers can easily bring this historical experiment into the classroom and build a bridge to modern applications in hyperspectral imaging and spectral encoding.
