How Light Affect Our Planet: Process Writing Thomas Tse October 31‚ 2012 Nowadays due to light pollution‚ it is hard to find a place in Hong Kong that can look at the stars clearly. It means that the light has disturbed our planet already; few types of animals can’t figure out that it’s morning or night. It affects the animal’s differentiation‚ communication and competition capacity. According to different problems‚ we must need to have some actions to help our society

the objects picture a description of what happens when light ray is shone on it. The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism‚ the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into a series of colours. This shows that white light is actually made up of many other colours - a fact first

Lights‚ Camera‚ Action. Light it up. As the popular Soca song goes‚ ‘Let me see you light up the Air’. Or Vybz Kartel’s song says ‘Light the Weed’. All focused around the presence of light. We cannot see without light‚ so in this regard‚ light illuminates our path. For this reason we ensure that our surroundings are fitted with lightbulbs. We cannot function in school or work or in life if there isn’t some measure of light. I’m here to enlighten you about the choice that you will face when purchasing

Light I | | INTRODUCTION | Light‚ form of energy visible to the human eye that is radiated by moving charged particles. Light from the Sun provides the energy needed for plant growth. Plants convert the energy in sunlight into storable chemical form through a process called photosynthesis. Petroleum‚ coal‚ and natural gas are the remains of plants that lived millions of years ago‚ and the energy these fuels release when they burn is the chemical energy converted from sunlight. When animals digest

LIGHT IN PHOTOSYNTHESIS Theory: Leaf discs float normally. When the air spaces are infiltrated with the solution the overall density of the leaf disc increases and the disc sinks. The infiltration solution includes a small amount of sodium bicarbonate. The bicarbonate ions serve as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy – causing the discs to rise. Since cellular respiration is taking place

Light is everywhere in our world. We need it to see: it carries information from the world to our eyes and brains. Seeing colors and shapes is second nature to us‚ yet light is a perplexing phenomenon when we study it more closely. Here are some things to think about: Our brains and eyes act together to make extraordinary things happen in perception. Movies are sequences of still pictures. Magazine pictures are arrays of dots. Light acts like particles—little light bullets—that stream from the

Sun light vs articical light One of the main benefits of artificial light is that you can control how many hours of light per day your plants receive. This way‚ those living in northern or southern latitudes can provide their plants with light for growth and development even when the sun sets early‚ in essence tricking the plants into believing that it is summertime and that they should continue to grow rather than become dormant or‚ in the case of annuals‚ die. In addition‚ your plants will receive

SOLAR BOTTLE BULB The solar bottle bulb is taking the developing world by storm bringing sustainable‚ affordable lighting to the underprivileged rural communities in a number of regions around the globe‚ the concept is cheap‚ simple and most importantly sustainable‚ but how did such an amazing idea come about? The concept was first conceived in 2002 by Alfredo Moser‚ a mechanic in Sao Paulo‚ Brazil‚ to light his workshop when his neighbourhood was suffering energy shortages‚ enabling him to continue
