reproduction. For plants‚ soil is needed to obtain these nutrients. Plants must also have light‚ air and water in order to grow. Light is a major component because plants need it in order to survive in their habitats because they use it to make food through photosynthesis. Light is also used to reflect off a natural green color‚ which is absorbed by the green pigment‚ chlorophyll. Aim What effects does sunlight and no light have on growing plants? The goal of this lab is to determine the effects of different

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

Silverstein PHY 101 Section 10497 March 4‚ 2013 Light up this World Purpose: In this lab experiment‚ LED lights will be used to show how when E&M radiation is absorbed‚ the energy is converted to heat. A drop of isopropyl alcohol will absorb light energy of different colors‚ and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs and circuits

audience. Shakespeare utilizes dim and light symbolism all through the play to represent death‚ savagery‚ trouble and mystery. In Act Two Scene Two Shakespeare utilizes dim symbolism to pass on Romeo’s misery. Montague portrays Romeo as making a counterfeit night which appears to mirror his dim‚ discouraged state of mind.

2-8 Refraction and polarization of light 5. Experiment Results A. Linearity of light 1. The light beam does go straight when we tested on the angle board. 2. As the source of light beam was getting farther away from the slit‚ the beam becomes narrower and shorter in addition to fading. This is because light particles escape more when they travel to go through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface
