- Figure 1. Ultraviolet Radiation Index across the World. The colors on this map of the world represent Ultraviolet (UV) Index values on a particular day in September 2015. The UV Index is a standardized scale of UV radiation intensity running from 0 (least intense) to 18 (most intense). The y-axis values are degrees of latitude, which range from the equator (0°) to the poles (90° north and −90° south). The x-axis values are degrees of longitude, which range from the prime meridian (0°) to the antemeridian (180° east and −180° west). (Source: European Space Agency,http://www.temis.nl/uvradiati on/UVindex.html.) I. Examine Figure 1 above and answer Questions 1–6. 1. Describe the relationship between the UV Index (the colored bar in Figure 1) and latitude (y-axis). 2. How do you explain the relationship between the UV Index and latitude? (In other words, why does UV intensity change with latitude?) 3. Find your approximate location on the map. What is the primary UV…A solution containing two different fluorescent compounds, Ben and Jerry, were analyzed for their individual concentrations in the mixture. Standards of pure Ben and pure Jerry were prepared at a concentration of 500.0 mM and were run in a UV-Vis Spectrophotometer to determine their absorption properties.
