研究目的
Investigating the composition of sunlight and the discovery of the solar spectrum through the use of prisms.
研究成果
Newton's discovery of the composite nature of white sunlight was a major breakthrough, though it was not fully exploited until much later. His work laid the foundation for the field of spectroscopy, despite the initial limitations and controversies.
研究不足
Newton's use of a circular aperture instead of a narrow slit limited the purity of the spectrum, preventing the observation of absorption lines. The resolving power of his setup was insufficient to clearly see the absorption lines.
1：Experimental Design and Method Selection:
Newton used a prism to refract sunlight into its constituent colors, observing the spectrum on a wall.
2：Sample Selection and Data Sources:
Sunlight was the source, passed through a small hole in a window shutter.
3：List of Experimental Equipment and Materials:
A triangular glass prism was used to refract the sunlight.
4：Experimental Procedures and Operational Workflow:
Newton darkened his chamber, made a small hole to let in sunlight, and placed the prism at the entrance to refract the light onto the opposite wall.
5：Data Analysis Methods:
Newton observed the spectrum and noted the separation of colors, concluding that white light is composed of a mixture of different colors.
