"Light" Essays and Research Papers

1 - 10 of 500


Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light is usually defined as having a wavelength in the range of 400 nanometres (nm), or 400×10−9 m, to 700 nanometres – between the infrared, with longer wavelengths and the ultraviolet, with shorter wavelengths. These numbers do not represent the absolute limits of human vision, but the approximate range within which most people can...

“Let There Be Light” 18 November 2013 Finding the Medium between Happy and Healthy The authors Douglas J. Lisle PH.D. and Alan Goldhamer D.C. wrote the book, The Pleasure Trap: Mastering the Hidden force that undermines Health and Happiness, to reveal to people how to live healthy yet happy lives. The authors did an adequate job of revealing to their audience how sleep is an important aspect to our happiness. They are able to do this by connecting Thomas Edison’s invention of the light bulb to the...

Phenomena of Light

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...

Liter of Light

energy can reduce the impact of pollution and global warming issue. “Liter of Light” operates with the theory of solar energy with using several materials. Solar energy is one type of popular renewable energy. Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. This technologies use the sun’s energy and light to provide heat, light, hot water and electricity for homes, business and industry. Current renewable...

Physics 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...

Light and Photosynthesis

Students are not expected to know the answers to the Prior 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...

Light Begins

"The light begins…the light ends" Dulce Maldonado Abstract: In this lab the students did two labs in which they learned the process of photosynthesis, which involves the use of light energy to convert carbon dioxide and water into sugar, oxygen, and other organic compounds. Oxygen is released as a product. This process is often summarized by the following reaction: 6CO2 + 12H2O ------> C6H12O6 + 6H2O + 6O2 The energy of photosynthesis comes from absorbed photons found in light and involves...

Light & Color

Essay 1: Light and Color The fascinating properties of light are not all detectable to humans, because our reference is mostly limited to what we can see. In order to determine the atomic/molecular composition of a fluid or gas, one must consult an emission and absorption spectrum. The properties of this spectrum include also waves, which can be any length, and define the spectrum of electromagnetic radiation. Ranging from gamma rays to radio waves, an electromagnetic spectrum includes each...

Reflection of Light

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...
