Introduction: Photosynthesis can be defined as light energy being converted into chemical energy‚ which is a very important process for plants and other organisms. Light can be described in terms of light quantity and light quality. Both of these have an affect on photosynthesis. The more light a plant absorbs the more the plant is able to photosynthesize. This light is absorbed though pigments which have specific interactions with certain light waves (colors). The goal of my first experiment

infrastructures‚ vehicles‚ stalls‚ and people. Lastly‚ you could only hear the engines of other cars as they pass by. But in a certain moment everything changed‚ there was a moment of pause in the air and the scene was different than before when the light had turned red. The blurred surroundings I have seen only a few seconds ago gradually cleared up and I could now see the busy people walking outside. There were some people going in and out of shops‚ some were looking through the windows‚ some

HOW TO SOLVE TRAFFIC PROBLEMS INTRODUCTION: The physical use of roads by vehicles‚ when traffic demand is great enough that the interaction between vehicles slows the speed of the traffic stream‚ this results in some congestion. When vehicles are fully stopped for periods of time‚ this is colloquially known as a traffic jam or traffic snarl-up. Traffic congestion has a number of negative effects‚ wasting time of motorists and passenger’s congestion reduces regional economic health. Delays‚ which

The Importance of Obeying Traffic Laws Traffic laws are designed to protect you and other drivers on the road. If we do not follow them we are not only putting ourselves at risk but also innocent bystanders and drivers. By knowing the rules of the road‚ practicing good driving skills and generally taking care as a road user‚ you help play a vital role in preventing a crash. You will also be making road safety policies more effective. Many factors play a role in road safety including following

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

in a better condition. Additionally‚ no driver should use mobile phones as we are not concentrated on the road when we are driving. All in all‚ it is high time more sterner traffic laws were imposed. The fact is that road safety can be achieved through multidisciplinary approaches involving road engineering and traffic management‚ education and training of road users‚ and vehicle design. If we still do not realise how serious is the problem of bad driving and poor road conditions the next casualty

Compound Light Microscope The familiar compound light microscope is a series of lenses (hence "compound") that focus visible light in such a way as to produce a magnified image. A single lens‚ often called a magnifying glass‚ cannot generally magnify images as much as a series of lenses although Antony van Leeuwenhoek‚ the first microbiologist‚ used a simple‚ albeit exquisitely crafted‚ lens to discover single-celled "animalcules‚" as he called them. Advantages: Basic compound light microscopes

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

Part I. Question 1 Aristotle uses two methods to prove light cannot travel. Besides his empirical explanation‚ where he observes that for the supposed motion of light to go “unnoticed from where the sun rises to where it sets is asking too much” (418b26)‚ he also provides an argument that is understood through the “light of reason.” (418b24) To understand his contention we must refer to his definitions of light and the transparent. The transparent is‚ for Aristotle‚ the medium of sight; it is “what
