There are two contrasting views that light either consists of particles or waves. Light is a perplexing phenomenon puzzled by Ancient Greeks and scientists for years. Even Issac Newton developed incorrect theories on light‚ when he was the inventor and genius behind physics. It has been proved that light can be both a particle and a wave. Human eyes collect light that is reflected from a source. For example‚ the light from a pencil comes from the source of light in the sun and travels to the pencil

Prynne‚ Pearl‚ and Arthur Dimmesdale by using the function of light and dark images in his writing. In Edgar Allan Poes The Fall of The House of Usher‚ the House of Usher is presented in the eyes of the narrator as a dark‚ foreboding house‚ and in an effort to reason in order to see things in a brighter light‚ looks into a mirror‚ but looking back at him are the eye-like windows of that dark and gloomy house. Poe uses chiaroscuro to express light images of the subject and then turn them into dark parallels

DISCUSSION Photosynthesis is a process of converting light energy into chemical energy and storing in the bonds of sugar. Photosynthesis takes place in the plant leaves. In the leaves‚ there are mesophyll cells that have chloroplasts‚ where the photosynthesis occurs. During experiment‚ two leaves were tested for the presence and localization of starch. One leaf was a light-grown plant with mask‚ and the other was a dark-grown plant with mask. Both leaves were soaked in iodine solution and then

The Effect of Different Light Colours on Plant Growth Dianne R. Calub Marshela Alpha B. Gesmundo BS-Environmental Science Prof. Jayson Antonio Chemistry Department January 04‚ 2012 Abstract The goal of this study is to learn how the colour of light affects photosynthesis‚ to identify the effects of different coloured lights on plant growth‚ and to identify the potential use of different light colours as a growth regulator. An experiment was performed with the help of 7 students. Mustard

as strong as it is‚ the demand for high quality light poles is as high as ever. This is apparent with any search for a residential light pole. A walk through your local hardware store will reveal a selection of hundreds of different designs from numerous manufactures. On a larger scale a search on the internet can be done to bring up thousands of different choices for a buyer considering making a purchase. For garden and pool areas shorter lights closer to the ground with less bulbs are available

Automatic Street Light Control System is a simple and powerful concept‚ which uses transistor as a switch to switch ON and OFF the street light automatically. By using this system manual works are removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. It automatically switches OFF lights under illumination by sunlight. This is done by a sensor called Light Dependant Resistor (LDR) which senses the light actually like our eyes.

The Northern lights‚ or Aurora Borealis‚ are one of the world’s most amazing phenomenons. The lights are the result of collisions between gaseous particles in Earth’s atmosphere with charged particles from the sun. Free electrons and protons are thrown from the sun’s atmosphere by the rotation of the sun. The charged particles are are largely deflected by the earth’s magnetic field‚ but at the north and south poles‚ the magnetic field is weaker‚ allowing some charged particles to collide with gas
