Light Refraction Research Paper

835 Words4 Pages

What is Refraction?
Refraction is the bending behavior of light when it passes through one medium to another. Especially when light travels from an optical dense medium to an optical less dense medium. The refraction of light relates to the change in the direction of which light travels which will then affect the change in the speed of light. When light changes the direction it travels, there will be a change in the wavelength; this change will then lead to the change in the speed of light. When light refracts within a medium, it changes the angle of the direction it travels which results in the change in speed. Light travels faster in less dense media (e.g Air) compared to a dense media (e.g Glass).

The image of an analogy of the marching soldiers on the right can assist us with these questions. The students represent the light rays (indicated by a blue ray), the masking tape represents the boundary that separates the two media; and the red ray represents the alteration of which the light travels once it passes the boundary. Light rays travel in a straight line towards the boundary, and when a light ray reaches the boundary and reaches the second medium, that light ray will change its speed. The light rays will continue to travelling until they all reach the boundary and enter the second medium. The arrows in the diagram show the direction that light travels in both media, we can also observe that the direction of the light changes at the boundary. The reason why the motion of the light will change its direction is due to the change in speed. After reaching the boundary, every light ray changes speed. The light rays approach the boundary at an angle (Perpendicular) and for this reason, light rays will pass the boundary at different times and refract. Generally, the direction that the light rays travel alters at the boundary. The change in speed of the light rays leads to a change in

    Caldesmon 1 is a gene that is located on Chromosome 7: 134.74 – 134.97 Mb which encodes a calmodulin binding protein. (15) The products of CALD1 such as Calmodulin- and actin-binding proteins play an essential role in the regulation of smooth muscle and nonmuscle contraction. (16) CALD1 inhibits ATPase activity of myosin in smooth muscle like calponin. Caldesmon (CaD) is an actin-linked regulatory protein found in smooth muscle and non-muscle cells.

    Before reading “Nickel and Dimed: On (NOT) Getting by in America”, my perception of blue collar Americans is much different. I had figured that blue collared workers in lower paying jobs were not very hard working people, and that they still made enough money to have decent living conditions. Before reading Nickel and Dimed I thought that if you had a job and were not making enough to get by that you were probably a lazy person. Reading Nickel and Dimed really opened my eyes to the quality of life workers in these jobs have made me realize that you can be employed at a Walmart or as a hotel maid like Barbara Ehrenreich was and still be living in poverty. I learned pretty early into Nickel and Dimed that only having one job at this level of jobs

  • Analysis Of A Divine And Supernatural Light

    In his 4th-century autobiography, Confessions, St. Augustine of Hippo describes his path from wickedness to righteousness. Knowledge of the self, he learned, facilitates one 's knowledge of God; comprehending the all-powerful demands self-assessment (Burt). How one may come to know oneself, and thus know God, preoccupied early American writers, who explored human transformation and perfectibility through a range of theologies and philosophies. Jonathan Edwards paved the way with "A Divine and Supernatural Light." With The Age of Reason, Thomas Paine abandoned Edwards 's mysticism in favor of rationalist principles, though Edwards 's belief in direct communication with the divine through subjective experience recrudesced in Ralph Waldo Emerson 's Nature.

    The plano-convex lens is replaced with another glass plate and a section of optical fibre was placed between them at one end. Light falling normally on the plates will be reflected back out with a phase difference. Figure 3: Apparatus set up for finding the thickness of an optical fibre, showing the optical fibre between the two glass plates This is due to the fact that some of the coherent light waves were reflected from the top plate and others from the bottom, this path difference resulted in the interference of these waves with one another. This caused an interference pattern similar to the below image: Figure 4: Image similar to the observed interference pattern.
