“Light Pollution” is a form of environmental pollution in which excessive artificial outdoor lightings affect the natural environment. Light pollution in Hong Kong is very serious. The main reason behind that are the artificial outdoor lightings. As there are many buildings scattered in Hong Kong‚ artificial lighting is omnipresent. The severe light pollution reduces the number of stars that are visible in the sky. The HKSAR Electrical and Mechanical Services Department‚ 20% of the total electrical

"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

As the sun rises‚ birds begin to sing the joy of light and as the day ends‚ the birds fly back into the darkness of night. The darkness of our lives is often transformed by the delusion of light. In James Baldwin’s essay‚ "Sonny’s Blues‚"� the title itself sets up an irony that is explored throughout. The name "Sonny‚" when read‚ sounds like "Sunny‚" meaning brightness‚ light and hope. The word "Blues" presents the reader images of night‚ darkness and sadness. The darkness represents the reality

I used to believe that love was a light switch. Something flicks on. You get an overwhelming sensation. It hits you like a bag of bricks. Or a strong arrow. When you know‚ you know. Right? Not so much. After 28 years‚ I don’t see love that way anymore. I’ve placed Cupid right next to Santa Claus and the Easter Bunny. Love is a series of choices. The first choice is based on many many factors‚ including chemistry‚ principle‚ logic‚ humor‚ intelligence‚ body type‚ where we are in our lives‚ what

In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis

Electromagnetic Wave from the sun such as light usually reflects horizontally off of surfaces. This process produces a super annoying glare that polarized sunglasses restrict from affecting your eyes. 3. In your own words‚ explain why we see a rainbow or colorful sunset. Explain the properties and interactions that make this display possible. (13 points) Sunlight is actually made up of a whole range of colors but when all these colors are combine it is seen as white. When the light passes through different types

Sudden Light di Dante Gabriel Rossetti I have been here before‚ But when or how I cannot tell: I know the grass beyond the door‚ The sweet keen smell‚ The sighing sound‚ the lights around the shore. You have been mine before‚-- How long ago I may not know: But just when at that swallow’s soar Your neck turn’d so‚ Some veil did fall‚--I knew it all of yore. Has this been thus before? And shall not thus time’s eddying flight Still with our lives our love restore In death’s despite

The Quality of Light Modern society has become so trivialized that true reality is not obvious to most of us. We accept the thoughts and concepts of others to be fact‚ and excuse ourselves from the bright and painful essence of the universe in which we were born. All my life‚ I have only seen shadows. Like the prisoners in the allegory‚ I had my “legs and neck(s) chained” (para.1) from childhood so as to only see what was laid out before me. I was unable to see the truth of the shadows‚ and

lesson‚ you need to know a little bit about light. White light consists of all the colors of the rainbow mixed together. Diffraction refers to various phenomena which occur when a wave encounters an obstacle. In classical physics‚ the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. Isaac Newton thought that light must be a particle because particles of light that travels in straight lines until they are
