Light Pollution 1. Every urbanite knows the bright lights of the city make it impossible to see the stars in a night sky. What most of us do not know is that those lights also may be making us sick. The cause is light pollution – the unearthly glow of billions of street lamps‚ security and porch lights‚ searchlights‚ office lights and signs – as people everywhere try to dispel the darkness of the night. 2. For the first time‚ light is being investigated seriously as a pollutant and a health hazard

My Green Light My green light is an ambiguous entity‚ consisting of multiple forms‚ each day varying from the next. This ever-changing pattern in my life is possibly a result of a void left behind from my childhood‚ as my parents had never encouraged or raised any desire to strive for a goal in me. As such I now have an inability to create a permanent goal for myself. My green light‚ in short‚ lacks conviction - it is deprived of the motivation required to maintain my interest‚ and eventually

Polarized light are those that are vibrating in one direction- in a single plane such as up and down. Those that are vibrating in more than one direction -- in more than one plane such as both up/down and left/right -- are called unpolarized light. Generally‚ unpolarized light can be considered to be vibrating in a vertical and a horizontal plane. To polarize light‚ one can transmit the light through a polariod filter which will only allow light of single polarity to pass. The resulting light will be

The Light Bulb: One of the Most Useful Inventions in the World People need light to be able to see. In the morning‚ there is sunlight. But in the night‚ people use electric light made from light bulbs. Without light bulbs‚ people would not be able to see and would have to rely on their other senses to do tasks. Without light bulbs‚ our lives would be very different. The light bulb is a very useful invention that people all over the world use every day. The creation of the light bulb can be traced

Speed of Light Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light. Other famous scientist‚ such as‚ Roemer‚ Foucault‚ Fizeau‚ Michelson‚ and Einstein added their own discoveries to the collage of information gathered through the years. Every scientist performed their experiments differently based on the knowledge and ability

The speed of light (meaning speed of light in vacuum)‚ usually denoted by c‚ is a physical constant important in many areas of physics. Its value is 299‚792‚458 metres per second‚ a figure that is exact since the length of the metre is defined from this constant and the international standard for time.[2] This speed is approximately 186‚282 miles per second. It is the maximum speed at which all energy‚ matter‚ and information in the universe can travel. It is the speed of all massless particles and

Day lighting in a building: is utilizing the available sunlight by manipulating window placement‚ window fixtures‚ and room dimensions to maximize natural light in a space. Benefits: It minimizes the need for lamps and overhead lights and the energy required to power artificial lighting. Daylighting improves

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
