Lab Executed: September 13‚ 2012 By: Arfan Rehab Colleagues: Edwin Chen‚ Tamzid Hassan‚ and Tony Zhao Abstract: The objective of this experiment was to measure the relative intensities of light at various horizontal distances from the lamp. The light detector (photocell) will enable us to make light intensity measurements that are more precise than those made with the human eye. The photocell converts light intensity to an electrical potential difference‚ which can be measured with

Environmental Pollution at Hindustan Lever’s Kodaikanal Plant In mid-2004‚ Hindustan Lever Ltd (HLL) executives looked back at the events of the past three years at their mercury thermometer factory in Kodaikanal in the south Indian state of Tamil Nadu. After mercury leakage from the plant had been reported in March 2001‚ heavy expenditure had been incurred in environmental risk assessment‚ waste disposal and health monitoring. The expenditure had exceeded the total profits generated by the plant

In the first chapter of the Orientation of critical theories entitled The Mirror and the Lamp (1953) M. H. Abrams concentrates on four main elements; the universe‚ the audience‚ the artist‚ and the work and relates them to four broad critical theories that explain the nature and worth of art. He explains that almost all theories will make use of at least one of these elements‚ some all four. That is a critic will derive from one of these terms his principle categories for defining‚ classifying and

our lives would be very different. The light bulb is a very useful invention that people all over the world use every day. The creation of the light bulb can be traced back to the 19th century. In 1800‚ Humphrey Davy made the arc lamp (“Lighting”). But the arc lamp was very dangerous because light was made by sparks‚ increasing the chance of fire (Burnie 52). In 1860‚ Joseph Swan made an incandescent light bulb. But the light bulb had many disadvantages. The light bulb burned out in an hour and

Usama Mazhar Kashif Ihsan Khattak Muhammad Imran Anwar ABSTRACT Light has started from the sunlight and moonlight‚ and then the fire has changed the concept of light. Humans made torches from wooden sticks‚ lamps from rocks‚ bones and pottery‚ candles from bee wax‚ oil lamps and gas lamps but fire was common thing in all these eras which actually produced light. Discovery of electricity made the light enter into new era of technology. Thomas Edison invented the incandescent bulb and then the technology

Plasma Complexity! Plasma is said to a substance similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds‚ rendering it into its constituent atoms. Further heating leads ionization‚ turning it into plasma: containing charged particles‚ positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic

Familiar examples are a candle flame‚ hot coals in a campfire‚ the coils in an electric room heater‚ and an incandescent lamp filament. Light is also produced during electrical discharges through ionized gases. The bluish light of mercury-arc

is made possible by using DPIP and observing its color change (Stegenga 24-8). In class‚ we observed this happening using a lamp and a spectrophotometer to measure the amount of light being transmitted through a test tube. Chloroplasts were placed into test tubes along with water‚ DPIP‚ and a buffer to neutralize the pH of the solution‚ and then placed under a lamp with a standard 40-watt light bulb. One test tube was used to calibrate the spectrophotometer so that each transmittance reading
