Light Emission and Absorption - Active Reading When atoms absorb energy‚ electrons can jump to higher energy orbitals. When the electrons move back to their original configurations‚ that energy is given off as light! Travel to the website linked below and take Cornell notes for each section. Write some big ideas in the left column and supporting details in the right column. Make sure to answer any questions given as well. Make sure you play and watch every animation and click every link

Knowledge Questions.] • To survive‚ what gas do we need to breathe in? Oxygen • Where is this gas produced? 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 produce‚ but most of it is released. In the Photosynthesis

immediate action to incorporation renewable energy sources is crucial. Specifically‚ the government should stop giving subsidies to oil companies and instead be using taxpayers’ money to develop solar energy‚ such as‚ solar thermal energy in order to establish a sustainable‚ clean‚ responsible and efficient form for energy for generations to come. While solar energy startup and even maintenance costs can be just as expensive as oil and coal production‚ solar energy is undoubtedly worth the price in the

THE NATURE OF LIGHT Until the time of Isaac Newton (1642–1727)‚ most scientists thought that light consisted of streams of particles (called corpuscles) emitted by light sources. Galileo and others tried (unsuccessfully) to measure the speed of light. Around 1665‚ evidence of wave properties of light began to be discovered. By the early 19th century‚ evidence that light is a wave had grown very persuasive. In 1873‚ James Clerk Maxwell predicted the existence of electromagnetic waves and calculated

Writing Practice Renewable energy has a positive effect on economy. Do you agree? As the fossil fuels resources have been continually mind in recent years. The lack of energy resources is one of the greatest challenges faced by government in Australia. Therefore‚ the new energy resources are promoted and developed such as nuclear power and renewable energy. Some in Australia argued that development of new energy resources not only alleviates the shortage of fossil fuels resources and protects

Of course‚ we live in an imperfect world and not all surfaces are smooth. When light strikes a rough surface‚ incoming light rays reflect at all sorts of angles because the surface is uneven. This scattering occurs in many of the objects we encounter every day. The surface of paper is a good example. You can see just how rough it is if you peer at it under a microscope. When light hits paper‚ the waves are reflected in all directions. This is what makes paper so incredibly useful -- you can read

Alternatively‚ contractionary monetary policy generally causes interest rates to rise. It personal saving increase as a result‚ the corresponding fall in consumer expenditure helps to slow the economy
