Scattering of Light | The scattering of light is an important observation in our daily life. The way light scatters off molecules in the atmosphere explains why the sky is blue and why the sun looks red at sunrise and sunset. This is because of the scattering of light. | | | Tyndall Effect A beam of light or laser‚ invisible in clear air or pure water‚ will trace a visible path through colloidal particles. This is known as the Tyndall effect after its discoverer‚ the 19th-century British

Essay 1: Light and Color The fascinating properties of light are not all detectable to humans‚ because our reference is mostly limited to what we can see. In order to determine the atomic/molecular composition of a fluid or gas‚ one must consult an emission and absorption spectrum. The properties of this spectrum include also waves‚ which can be any length‚ and define the spectrum of electromagnetic radiation. Ranging from gamma rays to radio waves‚ an electromagnetic spectrum includes each

“Light Pollution” is a form of environmental pollution in which excessive artificial outdoor lightings affect the natural environment. Light pollution in Hong Kong is very serious. The main reason behind that are the artificial outdoor lightings. As there are many buildings scattered in Hong Kong‚ artificial lighting is omnipresent. The severe light pollution reduces the number of stars that are visible in the sky. The HKSAR Electrical and Mechanical Services Department‚ 20% of the total electrical

The United States Beer Industry Over the last few decades‚ the United States beer industry has been characterized by a very clear trend toward an increase in the concentration of the market. Today‚ some 80% of all beer consumed in the United States is produced by just three companies-Anheuser-Busch (which is now owned by In Bev of Belgium)‚ SAB-Miller‚ and Molson Coors-up from 57% of the market in 1980. Anheuser-Busch had almost 50% of the market in 2008‚ up from just 28.2% in 1980. SAB-Miller (formed

Lights‚ Camera‚ Action. Light it up. As the popular Soca song goes‚ ‘Let me see you light up the Air’. Or Vybz Kartel’s song says ‘Light the Weed’. All focused around the presence of light. We cannot see without light‚ so in this regard‚ light illuminates our path. For this reason we ensure that our surroundings are fitted with lightbulbs. We cannot function in school or work or in life if there isn’t some measure of light. I’m here to enlighten you about the choice that you will face when purchasing

"The light begins…the light ends" Dulce Maldonado Abstract: In this lab the students did two labs in which they learned the process of photosynthesis‚ which involves the use of light energy to convert carbon dioxide and water into sugar‚ oxygen‚ and other organic compounds. Oxygen is released as a product. This process is often summarized by the following reaction: 6CO2 + 12H2O ------> C6H12O6 + 6H2O + 6O2 The energy of photosynthesis comes from absorbed photons found in light and involves

Is Beer Becoming More Concentrated? Oligopoly in the brewing industry At first glance‚ the UK brewing industry might appear to be highly competitive‚ with many pubs in close proximity to one another and with many brands of beer and lager offered for sale. However‚ in reality most pubs are owned by the major brewers. Tied houses‚ as they are called‚ account for about 40 per cent of a brewer’s turnover‚ and sell only a limited range of the beers and lagers that are available. Consumer

In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis
