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

The light bulb is an invention that has been around since the 1800’s. This invention has significantly‚ affected society by allowing the world to create a comfortable safe environment. The light bulb was invented in 1879 using lower current electricity‚ a small carbonized filament‚ and an improved vacuum inside the globe; this was not an original invention by Edison this was an improved invention by Edison from 50 years ago. Edison was able to produce a reliable‚ long-lasting source of light

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

Maybe on a big quest? This quote came from Thorin while talking about the quest. Thorin is very

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

sTraffic lights‚ also known as traffic signals‚ traffic lamps‚ signal lights‚ robots in South Africa[1] and‚ in the past‚ semaphores‚[2] are signalling devices positioned at road intersections‚ pedestrian crossings and other locations to control competing flows of traffic. Traffic lights were first installed in 1868 in London[3] and are now used all over the world. Traffic lights alternate the right of way accorded to road users by displaying lights of a standard color (red‚ yellow/amber‚ and green)
