14. Using two prisms, one after another, Newton demonstrated that: A. once dispersed by a prism, red light could be further spread out by the use of a second one, allowing him to distinguish 'ordinary' red light from infrared light B. once dispersed by a prism, sunlight could be recombined by an 'upside-down' prism to recreate white light C. the second prism would break the first continuous (rainbow-like) spectrum into a series of bright emission lines, the first real evidence that the Sun was gaseous in nature D. the second prism increased the detail he could see, allowing him to detect mysterious absorption lines in the solar spectrum
