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

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

significant to the story. The single green light on Daisy’s dock that Gatsby spends countless nights staring at across the lake is‚ in my opinion‚ the most significant image in the book. The light represents Gatsby’s unattainable dream to be with Daisy. He is so close to her yet so far. He fails to grasp this dream with her. I believe the green light represents the uncertain future. As Nick claims at the end of the novel “Gatsby believed in the green light‚ the orgastic future that year by year recedes

Dispersion Of White Light by a Glass Prism: When a beam of white light is passed through a glass prism‚ it is split up into a band of colours called spectrum. This is called dispersion of white light. The spectrum of white has the colours violet‚ indigo‚ blue‚ green‚ yellow‚ orange and red (VIBGYOR). The red light bends the least and the violet light bends the most. A rainbow is a natural spectrum appearing in the sky after a rain shower. It is caused by the dispersion of sunlight by water
