The episode was positively appreciated by critics, who noted in their reviews some plot and technical moves that were especially successful from their point of view [4] [5] . Also, compared with the previous episode, there is a noticeable increase in the number of U.S. viewers who watched the premiere of the episode live on Fox from 3.91 million to 3.98 million. Nevertheless, the rating in the age category 18-49 as well as in the previous episode was 1.5 / 4 [6] .
Story
The episode is devoted to the wave theory of light , studied by mankind. The study of light has become part of scientific progress, starting with such early experiments in this area as the creation of a pinhole camera by Chinese scientists Mo-tzu 2000 years ago. Tyson describes the work of an 11th-century Arab scientist, Ibn al-Khaysam , who is believed to be the first researcher in the field of optics, which led to the appearance of the telescope , as well as one of the first who began to apply the scientific method .
Tyson goes on to discoveries that have allowed humanity to understand the nature of light. He talks about the work of Isaac Newton , who refracted light using a prism and demonstrated that the light consists of the colors of the visible spectrum , as well as about William Herschel , whose experiments allowed adding infrared waves to the visible spectrum. In addition to the prism, Joseph Fraunhofer also used a telescope to view the spectrum in close-up, and found that there are longitudinal black lines on the color bars. It was later revealed that these Frauhofer lines are caused by the absorption of light when electrons move in the atoms of a substance from one orbital to another (the Bohr model of the atom is used in the show) when light passes through these atoms, and the location of the black lines is unique for each chemical element. This discovery subsequently formed the basis of astrospectroscopy , the main research method in which is to study the chemical composition of distant stars by identifying their color spectrum. This allowed astronomers not only to judge the composition of stars, planets and star clusters, but also to observe the motion of stars and the expansion of the universe, as well as to hypothesize the existence of dark matter .
Rating and reviews
The episode received positive reviews; critics praised the blues-style visuals at the end of the story, showing " Rhapsody in the blues style and" showing New York the way it is seen in light waves of various lengths: in the waves of the visible spectrum, infrared, ultraviolet, x-ray, microwave and gamma rays, and also in the radio range ” [4] [5] .
3.98 million viewers watched the premiere of the live episode on Fox . At the same time, the rating of the episode in the age category 18-49, as in the case of the previous episode, was 1.5 / 4. As a result, the episode took third and last place among the episodes of its time block, giving way to the episodes of the television series Resurrection and Believe ", And twelfth place among the fifteen premieres of the same night [7] .
