1. In 1884, a young engineering student from Germany, Paul Nipkow patented an electromechanical television concept which successively analyzed an image and transmitted it in order. He developed the first scanning device for television. His device was based on a discovery in 1873 which indicated that the electrical conduction varied depending upon the amount of light (photoconductive properties) a certain element received. The name of this element was: a. Gold b. Molybdenum c. Selenium d. Technetium e. Platinum press continue to finish the quest
