Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of

system came in place when Block Printing was around. During the Song Dynasty‚ authors started writing long scrolls and books. If authors wanted to publish their scroll or book‚ they would have to invest a lot of money and time. How did the Movable Type Printing change all of this? When an invention is made‚ it is made to solve a problem. In this case‚ the problem is the‚ Block Printing. This process is a very expensive and time consuming one. To ‘print’ a page‚ a block of wood would have to be carved

What is Light Pollution? Light Pollution Light pollution is artificial or outdoor light that creates glare and intrudes with the nighttime setting and the natural night environment. The artificial light that is produced by urban centres/ areas‚ diminish the view of stars and planets. These artificial lights can be seen all the way out in space! Satellite images show light pollution as well lit and glowing regions on a map at nighttime (see image below). These well-lit regions are mostly cities

Part I. Question 1 Aristotle uses two methods to prove light cannot travel. Besides his empirical explanation‚ where he observes that for the supposed motion of light to go “unnoticed from where the sun rises to where it sets is asking too much” (418b26)‚ he also provides an argument that is understood through the “light of reason.” (418b24) To understand his contention we must refer to his definitions of light and the transparent. The transparent is‚ for Aristotle‚ the medium of sight; it is “what

Without color or light‚ art would be nothing; we wouldn’t be able to see or distinguish anything. Light allows us to see the space about something; when it casts a shadow on something we know the size of something. Without color we wouldn’t be able to differentiate between anything. It allows us to see the edges of something which in turn allows us to form the relationships in size and space. Colors can also be used to accomplish a diverse sense of feelings. For example‚ artists can use colors to

Food Web Diagram The African Grasslands are areas where the vegetation is dominated by grasses and other herbaceous (non-woody) plants. Grasslands cover nearly 50 percent of the land surface of the continent of Africa. While grasslands in general support diverse wildlife‚ given the lack of hiding places for predators‚ the African Savannah regions support a much greater diversity in wildlife than do temperate grasslands. The root systems of perennial grasses and forbs form complex mats that

the speed of light “So far as problems involving light are concerned‚ the electrons (in atoms) behave as though they were held by springs”.Feynman “In a microscopic but otherwise classical analysis‚ the electric field in electromagnetic radiation accelerates electrons held by springs in the atoms of a piece of glass‚ and these accelerated electrons re-radiate in all directions. The observed light is the superposition of the electric (and magnetic) fields of the incoming light and the re-radiation
