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

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

The Green Light The green light at the end of Daisy’s dock is a significant symbol within the book. To Gatsby‚ the green light represents his dream‚ which is Daisy. To attain her would be completing Gatsby’s American Dream. The first time the green light is seen in the novel is also the first time Nick sees Gatsby. Fitzgerald writes‚ “…he stretched out his arms toward the dark water in a curious way‚ and‚ far as I was from him‚ I could have sworn he was trembling. Involuntarily I glanced seaward

“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

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
