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

When I first glanced at Nighthawks by Edward Hopper‚ I was thirteen years old and I was on a trip to The Institute of Art Chicago with my family. I was so intrigued by the painting that I took all the money I was given for the weekend and bought a reprint from the museum’s gift shop. The painting hangs on my wall in my house and has been on every wall in every home I’ve lived since I was thirteen. The meaning of the painting has changed for me over the years as I have matured and learned more about

“A Modest Proposal”‚ by Jonathan Swift is a graceful‚ frank and delusional piece of literature. It was written in the 1800’s to both comment on the ever-growing list of ridiculously useless and uninformed proposals written to help the Irish out of their temporary rut of poverty and famine‚ and to “Under the present situation of affairs‚ it is utterly impossible by all methods hitherto proposed…” Swifts calm and straight forward manner would lead a reader - not paying close enough attention‚ to view

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

question of the female divine; the varied criticisms and the study of the scriptures where God declares to Moses “I am that I am.” The article goes on to defend the male divine in that it argues from religious studies‚ scriptures and published studies the male nature of God from a Christian’s standpoint.

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
