sTraffic lights‚ also known as traffic signals‚ traffic lamps‚ signal lights‚ robots in South Africa[1] and‚ in the past‚ semaphores‚[2] are signalling devices positioned at road intersections‚ pedestrian crossings and other locations to control competing flows of traffic. Traffic lights were first installed in 1868 in London[3] and are now used all over the world. Traffic lights alternate the right of way accorded to road users by displaying lights of a standard color (red‚ yellow/amber‚ and green)

Light pollution happened slowly at first which was several decades ago it was a process that was hardly noticeable. A light here‚ a light there‚ burning way into the dark nighttime realm‚ helping us see in the darkness when people all their our beds fast asleep. The process still continues today‚ with little thought ever given to what we are stealing away. Our intentions are good but our methods need adjustment‚ and they needs to be done immediately. In fact‚ our methods should have been changed

energy can reduce the impact of pollution and global warming issue. “Liter of Light” operates with the theory of solar energy with using several materials. Solar energy is one type of popular renewable energy. Solar energy‚ radiant light and heat from the sun‚ has been harnessed by humans since ancient times using a range of ever-evolving technologies. This technologies use the sun’s energy and light to provide heat‚ light‚ hot water and electricity for homes‚ business and industry. Current renewable

kinds of artificial light sources for photography Light‚ is the main ingredient in a photograph. There are of course other ingredients: time‚ composition‚ subject matter‚ emotion and your unique style‚ but light is the thing that makes photography work. Light is the thing that early inventors had to hold or fix‚ in order to make a photograph stick around. We call nature’s light‚ natural or available. Think of sunlight or moonlight. There are four common types of artificial light sources used in photography

Light is just one portion of the various electromagnetic waves flying through space. The electromagnetic spectrum covers an extremely broad range‚ from radio waves with wavelengths of a meter or more‚ down to x-rays with wavelengths of less than a billionth of a meter. Optical radiation lies between radio waves and x-rays on the spectrum‚ exhibiting a unique mix of ray‚ wave‚ and quantum properties. At x-ray and shorter wavelengths‚ electromagnetic radiation tends to be quite particle like

HVDC LIGHT TECHNOLOGY ABSTRACT [pic] Transmitting power at high voltage and in DC form instead of AC is a new technology proven to be economic and simple in operation which is HVDC transmission. The HVDC (High Voltage Direct Current) technology is used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems. A further development in this technology is HVDC

Properties of Light Purpose: The ideal purpose of this lab activity is to investigate the relationship between the frequency of the light (color) and the energy produced by different colors of light. Other purposes of this experiment include calculating the proper current for each LED‚ measuring the evaporation rate of rubbing alcohol‚ and being able to discuss the outcome of the relationship in light energy and the color of the light producing the energy. Materials: Light Emitting Diodes
