Revealing the nature of the final image in Newton's experimentum crucis

“…Direct-vision prisms have a larger dispersion angle than simple ones, allowing us to double the field of view to about 5 . 41,42 As expected, the final image is a rainbow-colored image of the sunlit scene (Fig. 11).…”

“…The distance from H to A is 1.5 m. Through direct-vision prism P2, a camera photographs toward A from a distance of 1 m. For maximum image sharpness, P1 is not inverted relative to P2 (Ref. 41). (b) Pinhole H (made triangular to show that the shape of the hole does not significantly affect the projected image) and prism P1.…”

“…41 A video is projected through the first prism and onto a white thread, or, more conveniently, an uncooked spaghetti noodle. Sitting in a circle around the spaghetti, students can view through the second prism a sharp, rainbow-colored version of the video.…”

“…Sitting in a circle around the spaghetti, students can view through the second prism a sharp, rainbow-colored version of the video. 41 This projection method epitomizes the nature of the final image in Newton's experimentum crucis: It is a rainbow-colored representation of the initial image. 47 …”
