Essays on Mirrors

Reflection and Refraction of Light

REFLECTION: Reflection of light is the change of direction that light experiences when it collides with an object and "bounces." The reflection of light makes it possible to see objects that do not emit their light . There are several applications of the reflection. One example is the "The Laugh House" of an amusement park, the person will probably see a very distorted image in a curved mirror. Similar deformations occur in the concavity of a shiny spoon or on the polished surfaces of a coffee machine or a car. Images look different due to irregular surface curvature; They have ...

Abstract

A sandstorm is characterized as one that whips up extraordinary loads of sand into the air, forming a dense cloud above the ground in the process. While most of the sand will rise higher than 50 cm, some sand particles can even ascend to the height of 2 meters. According to Wikipedia, the average diameter of the particles carried by such dust storm winds will vary between 0.15 and 0.30 mm. Wind speeds such during sandstorms have been recorded at up to 16 km per hour and more, while most storms continue to blow for between three hours to ...

This is a concept that is popular in Victorian Literature and helps to drive the plot as the conflict is often times essential to the advancement of the storyline. ...

Solar Energy

Solar Energy Background What can be more useful for humanity if not an unlimited power source, which we can use without any harm to the environment? Probably nothing, but solar power. Humanity has always tried to conquer the unlimited power of the sun – the history of solar technology dates back to the 7th Century B.C. and continues to this day. In the beginning, we tried to concentrate the sun’s heat by using glass, mirrors or other devices to light fires. From those times, we greatly progressed, but still we did not conquer this magnificent source of power. Why ...

Rock and roll began to emerge shortly after the Second World War somewhere in the mashup of cultures and peoples that comprise the American South. It is a hybrid form whose mixed heritage is marked by poor blacks singing Delta blues, hillbilly descendants of Scots-Irish immigrants, working-class factory heroes, Christian country folk, and urban teens crooning a cappella on street corners. Its journey of 70 or so years has taken it from the margins of society to the center of today’s multi-billion dollar global music industry. Its course can be charted by examining a select handful of the ...

Use of Fossil Fuels for Power Generation and the Need for Renewable Energy

According to Nelson (2011), more than 85% of the world’s energy consumption, which is estimated at 520 exajoules, is generated through the burning of fossil fuels such as petroleum, natural gas and coal (p.19). Electric power generation from non-renewable sources will, unequivocally, result in their exhaustion and creation of a major energy crisis. For this reason, it appears primordial to shift in a greater scale to alternate power generation, such as solar, wind, hydroelectric, etc. Amongst these, Sorensen (2011) explains that though hydroelectric power does represent one of the major forms of power generation, its growth is stagnant ...

Gabriel Garcia Marquez’s Love in the Time Cholera and Yasunari Kawabata’s Snow Country are two novels that redefined the contours of Latin American and Japanese literature. Kawabata’s writing style and magical realism went on to win him a Nobel Prize in Literature while Marquez became one of the best writers of the 20th century. In both texts by Kawabata and Marquez there is a constant struggle between tradition and modernity. Water is a significant recurring motif in Love in the Time of Cholera inasmuch as it reflects on the struggle of the main characters to balance ...

Literary works have always been the mirrors of the society, and many of them have come to critique the subjugation of women. One can take into consideration the literary works, The Awakening, by Kate Chopin and Henrik Ibsen’s A Doll’s House that delve into the influences of the society and the family in oppressing women. The respective narratives would lead to a better comprehension of the intricate influences and experiences that finally pave the way of the emancipation of the characters of Edna and Nora from the shackles of patriarchy and subjugation. A comparative analysis of the ...

The short story “The Cask of Amontillado” that takes an honored place in Poe’s gallery of nightmares and horror accurately ...

Solar Power Generation

Sustainable Technology – Solar Power Generation Power Generation from Fossil Fuels and Global Warming Global warming, as defined by Lineman, Do, Kim and Joo (2015), is the long-term trend of increasing average temperature of the lower atmosphere. It is widely known that this phenomenon is related to the concentration of greenhouse gases that trap heat in the atmosphere, such as carbon dioxide, methane, nitrous oxide, among others. Activities related to human development such as industrial processes, agriculture, cattle raising for meat consumption, transportation, deforestation and power generation are the major causes of greenhouse gases emissions. Specifically, power generation based on ...

Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

            The generation of electric power through the exploitation of fossil fuels, such as coal, oil and natural gas, is one of the main factors influencing climate change due to the greenhouse gases emissions resulting from the process. In consideration, there is an increasing need to shift towards systems of power generation derived from renewable sources, which have a significantly lower environmental impact; among these are solar, wind, geothermal, hydraulic and ocean power generation. This essay will focus on solar power generation. The energy contained in sunlight can be converted into electricity through the use of Concentrated Solar Power systems ( ...

In terms of both our vocations and hobbies, we often aspire to become great. What happens, however, when this very desire consumes and overtakes us? The 2010 film "Black Swam" starring Natalie Portman as a high-profile ballet dancer, shows its viewers that unchecked ambition can be a dangerous and ultimately deadly thing. This message is achieved primarily through the film's use of detail-heavy camerawork, its character depiction, and its embrace of magical realism and distortions of reality. The main character Nina loses her identity, herself to become perfect and on this way to the culmination of her transformation she ...
