Supply Curve Shifts Student Feb 17‚ 2013 Principles of Microeconomics The Supply Curve: Price is usually a major factor in the quantity supplied to the market. For a particular good with all other factors held constant a table could be constructed of price and quantity supplied based on observed data. This table is called a supply schedule‚ example: Supply Schedule Price Quantity Supplied 1 12 2 28 3 42 4 52 5 60 By graphing this data the supply curve is created:

Which color of the spectrum of sunlight yields the highest temperature? My hypothesis is that the blue/violet part will have the highest temperature. The blue/violet part has the highest frequency out of all the colors on the visible light spectrum and it also has the highest amount of energy. Therefore‚ I hypothesize that it will have to the highest temperature as well. After conducting the experiment‚ I noticed that during the duration of five minutes‚ the temperatures of all four thermometers
