Reflection and Refraction Research Paper Example | Topics and Well Written Essays - 1000 words

Reflection and Refraction - Research Paper Example Also, it has aided in the understanding on what makes the objects visible. The law of reflection The rule of reflection holds â€Å"for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected† (Anonymous, 2010). Reflection occurs when the wave travels through one medium to another. This is referred to as refractive index of the media. I order to determine the refractive index of different media, the following formula is used; n=c/v whereby, â€Å"n is the refractive index of the material, c represents speed of light in vacuum and v is the speed of light in vacuum† (Reeves, 2008). According to the law of reflection, the angle of incidence and the angle of reflection falls on the same reflecting surface and are equal and on opposite sides of the normal line (Kosso, 1998). Also, there is an assumption of a normal line which is an imaginary line perpendicular to the plane mirror surface and is the central line bet ween incident and reflected lines (appendix 1). When reflection occurs on an even surface, it forms a mirror image which appears overturned from right to left. However, when specular reflection occurs at a curved surface, these forms magnified or de-magnified images. Causes of reflection The nature of reflection depends on the surface in which the waves come into contact with (Jacobs & Schulman, 2008). ... Diffuse reflection of light waves enables us to see the various objects after coming into contact with various objects. In some situations, the reflected waves return in the direction they came from. This is referred to as retroreflection hence this makes the object to appear brighter (Reeves, 2008). Also, it is possible for reflected waves to undergo further reflections after coming into contact with another surface. This is referred to as multiple reflections (appendix 2). For example, this is observed if two mirrors are placed opposite each other and then an image is placed between them. Infinite images are formed on each mirror due to the occurrence of multiple reflections. Application of Reflection Reflections of waves of energy have numerous uses in daily lives. For example, the reflection if light waves are used in x-rays whereby, the light waves are converged and focused at a point to generate immense energy appropriate for the activity (Jacobs & Schulman, 2008). Different ma terials have different refractive indices hence when energy wave moves from dense to less dense refractive index materials; the reflected wave is diverged away from the normal. On the other hand, a movement of energy wave from a material with a less dense to a material with denser refractive index, the reflected wave is deflected to the normal line. The knowledge of reflection has also been applied in radar to manage the operations of aircrafts at the airport (Kosso, 1998). The same knowledge is also applied in radio and television broadcasting among other areas. The characteristics of waves can be viewed in the water bodies or as electromagnetic waves such as visible light. Conclusion When waves come into contact with

Robinson fruit shoot market share Essay Example | Topics and Well Written Essays - 1500 words

Robinson fruit shoot market share - Essay Example To understand better preference and market share, it was worthwhile taking the time to study previous reports on the Robinson Fruit Shoot brand that had been compiled earlier by different studies. This helped the researchers go to the field with knowledge of the perception of the brand and an expectation of opinion. This, however, could, however, influence the objectivity due to response anticipation. From the studies done by Mintel, Fruit Juice, Juice Drinks, and Smoothies - UK - November 2012 and Fruit Juice and Juice Drinks - UK - November 2011 placed Robinson Fruit Shoot at number three and number two respectively as a market share player. They proved that the Shoot was popular among the other brands but was not in pole position as to control the market. That, therefore, seemed to suggest that more marketing and sales were required so as to make the brand the market leader. From another survey by Mintel for Cordials and Squashes in October 2012, there was increased demand for sof t and low alcohol drinks in the United Kingdom hence showing that there was an increasing market for the Shoot as more, consumers preferred soft drinks. The third survey used in the secondary research was Fruit Juices, Energy & Juice Drinks Market Report 2013 that showed the preferences of the children aged between 1 to 15 years, the target consumer group. The survey’s findings are important for the marketers of the shoot to execute a marketing plan that carters for the children’s taste and preferences.
