Investigating Correlation Between Angles Of Incidence And Angle Of Refraction
In the first part of this experiment we used a flat, concave, and convex mirror to determine the relationship between the angle of incidence and the angle of reflection for a light rays reflection on these mirrors, seen in Procedure A. In the second part of this experiment we used a light source, a threeway mirror, a rhombus prism, and a protractor to measure angles of a light ray. All of these instruments and devices were used to examine the relationship of the angle of incidence and the angle of refraction for a light ray passing through a rhombus prism, seen in Procedure B. Lastly, in the third part of this experiment we used an acrylic rhomboid to observe the dispersion through the lens, seen in Procedure C and then proceed with calculating the different indices or refraction for different colors of light, seen in Procedure D.
Theory
Part A: Reflection
We observe the Law of Reflection, which states that the angle of incidence will equal the angle of reflection coming from a beam of light. As Procedure A will show, when a beam of light is directed on a mirror being either flat, concave, or convex the beam of light will change directions according to the mirrors. The angle between the normal line and the first beam is known as the angle of incidence, (ϴi). The angle between the normal and reflected beam is known as the angle of the reflection, (ϴr). With these symbols we obtain the equation: ϴi= ϴr
Part B: Refraction
When a beam of light is directed…

Angle of Shooting in Soccer
1434 Words  6 PagesIn playing soccer, many aspects are crucial in scoring a goal: a shooter’s performance, the formation of the defenders, etc. In this paper, dimension of a soccer field will be analyzed in order to find a shooting position that provides the widest angle for a soccer player to shoot. Analyzing a soccer field According to FIFA (Fédération Internationale de Football Association), the dimension of a standard soccer field is 90m120 m in length, and 4590 m in width. Because of the variation…

Investigating The Correlation Between Surface Area And Volume
1827 Words  8 PagesAIM To investigate the relationships between the shape of an object and the time taken for a substance to diffuse into its center and to investigate the correlation between surface area and volume in regards to cellular transport. BACKGROUND THEORY / INTRODUCTION Cells are the basic unit of life of which all living organisms are built upon, they are the smallest living organizational unit and they all come from preexisting cells which has been supported by several scientists in the formation of…

Investigating Correlation Between A Solution Salt Concentration And Its Density
1135 Words  5 PagesThe objective of this experiment is to determine the correlation between a solution’s salt concentration and its density. Also, it was to determine what equipment would be best to use to measure volume precisely and accurately. Densities of a series of known salt solutions were trialed three times and then averaged. By following the procedures, the unknown salt solution was determined and graphed to calculate the percent salt to the sample. Introduction In chemistry there are often times an unknown…

Explain The Concepts Of Reflection, Refraction, Dispersion And Brewster 's Angle
1436 Words  6 Pagesdifferent experiments were performed to explain the concepts of reflection, refraction, dispersion and Brewster’s angle. The purpose of the first experiment is to analyze the incidence and reflection angle to understand how light reflects off a flat, convex, or concave mirror. In the second experiment a light ray is passed through a rhombus prism to discover the relationship between the angle of refraction and incidence. For the third experiment calculations were made to find indices for the color…

A Relationship Between Shoulder Flexion Angle And Mobility Measured Through A Tug Test
859 Words  4 Pagesflexion angle in the loaded knee is reduced with more severe knee osteoarthritis (OA)1. Loaded knee flexion range of movement (ROM) has also been demonstrated as a useful parameter in discriminating between patients with knee OA and controls2. As knee OA is a disease that results in the reduction of mobility, and loaded knee flexion angles have been previously positively correlated to Hospital for Special SurgeryScore (HSS)3, our investigation looked at the relationship between knee flexion angle and…

Critical Angle And Total Internal Reflection
1312 Words  6 PagesCritical Angle & Total Internal Reflection Kate Graham Partner: Samantha Dekart Monday, November 9, 2015 SNC2D Ms. Vink Purpose: See attached sheet, labelled “SNC2D Lab Sheet”. Related Theory: Law of Reflection: Reflection and refraction are common properties of light. When a ray of light comes into contact with the surface of some material, part of the ray is reflected and part of it is absorbed. In other words, reflection occurs…

Glaucoma And Closed Angle Glaucoma
1143 Words  5 Pagescauses damage, and this is called glaucoma. This condition can be traumatic for the patient as it has no cure. There are two categories that will be discussed in this paper and they are open angle glaucoma and closed angle glaucoma (The glaucoma you may be missing, 2013). Closed Angle Glaucoma Closed angle glaucoma (CAG), or acute glaucoma, stems from a narrowing or blockage through the pupil from the posterior chamber to the anterior chamber and causes the iris to stick out or protrude until it…

Season and Axis Angle
2012 Words  9 PagesWarmup The reasons for seasons have a lot to do with the angle at which the Sun’s rays hit Earth. To see why, select the PLATE tab on the Seasons: Why do we have them? Gizmo™. The image shows a solar panel (Plate M) facing the Sun. Check that the Axis angle is set to 0˚. 1. Click Fire to release 100 “rays” of sunlight. Look next to “Number of hits” below the plate. How many of these rays hit Plate M? 100 2. Click Reset. Change the Axis angle to 40˚, and click Fire. How many rays hit Plate M now…

Investigating The Correlation Between Non Financial Factor And Valuation
963 Words  4 Pagesdata is used to derive the regression model analysing the relationship of the human capital of the founding team and valuations placed by the VC investors. The dataset for the regression model intended to investigate the statistical relationship between the nonfinancial factor and valuation is collected from Pitchbook. Since valuations in VC rounds are often highly confidential, the sample size is quite small, including 107 companies with 230 founders in total. However, as elaborated in section…
