Question and answer
Q: 1. Newton’s prism experiments showed that white sunlight is made up of (1 point)the full electromagnetic spectrum. only blue light. all the colors of the visible spectrum. only the longest
wavelengths.
A: y 300 BC, Greek scholars had begun to study and contemplate optical phenomena generating theories to explain vision, color, light, and astronomical phenomena. [ Many of those theories turned out to be wrong, but they did serve to inaugurate the science of optics. During the second century AD, Ptolemy, a Greek astronomer based in Alexandria, Egypt, studied and wrote about many topics in
science. He published five books about optics, but only one book has survived to the modern era. This series of works was dedicated to the study of color, reflection, refraction, and mirrors of various shapes. Few other advances were made in optics until after 1000 AD. The Arab scholar Alhazan, a.k.a. Abu Ali Hasan Ibn al-Haitham, conducted the first serious study of lenses in Basra (Iraq). He studied refraction in lenses, and also carried out research on reflections from spherical and parabolic mirrors. His writings were the first to explain vision correctly, as a phenomenon of light coming into the eye, rather than the eye emitting light rays. The term “light” is often extended to adjacent wavelength ranges that the eye cannot detect - to infrared radiation, which has a frequency less than that of visible light, and to ultraviolet radiation, which have a frequency greater than that of visible light. This is the attitude employed by the editors of this page. ]
