Light Rail Transit is the most recent innovation in public transport technology and is regarded by many major municipalities across Canada as the next step in the evolution of their public transit systems. Many municipalities have begun plans to implement LRT within the near future, and Hamilton is one of them (“Ten Year Local Transit Strategy”). Light Rail Transit has many benefits: it is relatively inexpensive to produce, and the cars themselves are high capacity (about 280 people in a…

the world needs. Then I go ahead and try to invent it.”-Thomas Edison. In the 1800s’ the only source of light available at night was from fires, candles, and oil lamps which always presented a fire hazard and emitted a smelly odor when used. This gave Edison the idea of creating an alternative source of light with the newly discovered energy, electricity. Invented in 1879, the incandescent light bulb became one of the biggest factor in revolutionizing people 's’ lives. It gave people the power…

connected to Arduino board. This was done by calibrate part by part which is started with LDR sensor, then PIR sensor and lastly LED as light module. During day, all LEDs and PIR sensor is turned off. This condition is shown in Figure-10. Figure-9. Prototype of proposed design project Figure-10. Condition during day During night, whereby LDR sensor detects light intensity, 4 LEDs at the junction will turned on. This is called as Mode 1. Figure-11 shows the…

Gelatin to measure the speed of light My project is based on the speed of light and how I am able to measure it only using a protractor, a laser, and some math. The research paper will include the following questions; How can we use gelatin to measure the speed of light? Who discovered the ability to measure the speed of light? When was the speed of light discovered? Why is the speed of light important? What is the speed of light? And where was the speed of light discovered. Research Questions…

Exploration: Research Question: How does the travel distance of light waves affect the distance between the constructive interference fringes in the Double Slit experiment? Personal Engagement/Topic: Light is seen everywhere, artificial and natural. It is so common, that no one really questions it. But what is light made of? Intuitively, I would answer that visible light is a particle. It makes sense, doesn’t it? The photon from the source shoots into the eye’s retina, and the eye’s rods and…

Introduction The electric light bulb has basically remained unchanged for over a hundred years. The new federal energy-efficiency standards have taken effect and are pushing out the old uneconomical light bulbs for more efficient options, such as light emitting diodes. The primary function of LED lighting is for the preservation of energy. This composition will furnish information to home owners about the advantages of shifting to LED lighting, by contrasting the benefits of modern LEDs to the…

when talking about a light bulb’s performance is the brightness. The brightness of a light bulb is measure in lumens (lm). It measures how much light the bulb outputs so the more lumens, the brighter the light. The power consumption is also important to know how many lumens a bulb produces per watt. The ratio of total output lumens per total watts used to power a light bulb is called luminous efficacy. Figure 2 shows a table comparing the luminous efficacy of each type of light bulb.…

Based on a true story, “The Charge of the Light Brigade” inspired many with the genuine war cries. The poem tells the story of a brigade consisting of 600 soldiers who rode on horseback into the “valley of death” for half a league. The reasons for the poem’s popularity should be evident because it is such a stirring expression of courage under fire, heroism under impossible odds, of the might of the English military. In “The Charge of the Light Brigade,” the author used setting, imagery, and the…

fought against Russia by Britain, France, the Ottoman Empire, and the Kingdom of Sardinia. One complication in the war was that the British Light Brigade ran into Russian fire, in which 600 British horsemen were surrounded. They were fired at, and in the end, 278 of the Light Brigade soldiers either were injured or killed. The poem “The Charge of the Light Brigade” by Alfred, Lord Tennyson reflects how intense the firing was, how loyal and unquestioning the soldiers were, and how brave the…

For this project, I looked at the light pollution condition around my parents’ house in Western Springs, Illinois. Western Springs is a small suburban community on the southwestern edge of Cook county, about fifteen miles west of Chicago. By being so far outside the city, light pollution is not very significant but is still somewhat present, especially when viewing the horizon. However, the skies directly upward are fairly clear, and you can see starts and planets with relative ease on a…
