In plants Gizmo Warm-up During photosynthesis‚ plants use the energy of light to produce glucose (C6H12O6) from carbon dioxide (CO2)‚ and water (H2O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. A by-product of photosynthesis is oxygen. Plants use some of the oxygen they

Brazil‚ to light his workshop when his neighbourhood was suffering energy shortages‚ enabling him to continue working. His neighbours‚ intrigued by the idea‚ soon started following suit‚ adding the bulbs to their homes in kitchens‚ bathrooms and living areas where electric light was prohibitively expensive and inefficient. The bottle bulb revolution was then further enhanced by The “MyShelter Foundation”‚ which runs a program in the Philippines called “Isang Litrong Liwanag: a Liter of Light”. Based

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)

in the day time. Having observed these problems being encountered‚ this project will be developed to bring about the automation of the switching of lighting system using light depending resistor (LDR). The project is an electronic switch that is controlled (turned on and off) by the amount of light shining on the LDR. When light strikes the LDR‚ the switch opens (turns off); when the LDR is in darkness‚ the switch

I believe that the following commentary was effective in achieving its purpose. In the text‚ Ana Rand presents the event as human greatness by using pathos and vivid illustrations. She starts with an eloquent description saying that the launch of Apollo 11 "began with a large patch of bright‚ yellow-orange flame shooting sideways from under the base of the rocket." This description helps an audience form a visual picture of the event. Most Americans would have already seen the remarkable and proudful

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.

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
