that played an important part in this production was the lighting. The Lighting crew put an old light fixture in the middle of the room of the set. One light worked and there was one blown out. This gave the audience an even better idea of the characters and their life. The one working light bulb showed the economic stature of the two brothers. Also‚ there were breaks in the scenes where the lights would go out for the characters to leave the stage and get prepared.

assessment criteria 5 and 6 The Photoelectric effect‚ and the Production of Light In 1887 Hertz discovered the photoelectric effect‚ where electrons were emitted from a zinc surface when illuminated with ultra-violet light. These electrons (called ‘photoelectrons’) were only emitted when the frequency of the ultra-violet light was above a certain value (called the ‘threshold frequency’). Criteria 5c Assume that ultra-violet light is falling onto a piece of zinc‚ and photoelectrons are being emitted

Pollution of Hussain Sagar Lake Man is a selfish animal. Nature has been its main victim since time immemorial. Man is basically responsible for polluting the environment. But what have we done about it? The pathetic condition of Hussain Sagar Lake speaks for itself. WHAT A pity for the Hussain Sagar Lake at Hyderabad. It is a mean act by the educated Hyderabadis. The Hussain Sagar was actually developed by the early Nizams‚ for depicting the glory of Hyderabad. But‚ if you get to know how

The Effect of Light Intensity The effect of different light wavelengths was tested in the following experiment. The rate of photosynthesis can be affected depending on the light treatment it receives. With the aid of DPIP acting as NADPH in photosynthesis‚ it was possible to observe the reaction as it took place. Samples were created with dark‚ 24 cm‚ 30 cm‚ and 49 cm light treatments. The absorbance was measured in five-minute intervals for each sample and recorded in an appropriate table

Causes and Effects of Water Pollution Public Service Announcement for Pollution What are the causes of water pollution? This question has no simple answer. Water pollution can be defined as anything humans do to cause harmful effects to our bodies of water. This can include pollution of rivers‚ lakes‚ oceans‚ and ground water pollution. The causes of pollution in the water are virtually endless. Manufacturing plants are major causes of water pollution‚ using bodies of fresh water to carry away

Light Lab Report Introduction: Without light‚ plants would not be able to carry out photosynthesis (McKenney‚ Peffley‚ and Wilmington 49). Photosynthesis is responsible for providing the plant with nutrients it needs to thrive and grow. Without the proper nutrients‚ it is difficult for a plant to continue to live. Therefore‚ photosynthesis is necessary for a plant’s vitality. The goal of this experiment is to observe and identify the impact that light has on a plant. Hypothesis: If light

Ocean Pollution It is believed that 4.6 billion years ago our Earth was formed. And over 200 million years ago the great body of water on this planet‚ what we call the ocean‚ was able to be formed (History of the Ocean). For 200 million years our ocean has flourished with the life of all matters of creatures from some of the first ever cells to take life‚ to pre-historic dinosaurs‚ to the fish‚ plants‚ and mammals we see today. However‚ today we face a new point in the history of our ocean. Today

Light Intensity Experiment: For the light intensity experiment‚ our first set of data illustrated strange correlations between the three tubes placed in front of a light source‚ so the data provided in e-campus was used. The tube that was 24 cm away from the light had the greatest decrease in absorbance over the course of 20 minutes‚ followed by the 30 cm and then the 49 cm light apparatus. The tube that was placed in the dark (wrapped in foil) remained a dark blueish-green color whereas the tubes

because blue light has a higher absorbance by plant photosynthetic pigments and has a higher energy wavelength than red light‚ we predicted that juniper needles placed in blue light would photosynthesize faster than juniper needles placed in red light. We measured the rate of change in CO2 concentration due to juniper needles. For each sample‚ we placed the needles into a chamber connected to the CO2 monitor and measured the rate of change of CO2 concentration for 10 minutes under red light and then

Air Pollution Are you doing everything you can do to live a long and healthy life‚ eating healthy‚ exercising? Well that might not be enough‚ everyday the air you breathe can reduce life expectancy by 2 to 3 years; and an estimated total number of 6.3 million deaths caused by air pollution (Air Pollution kills). Air pollution has been going on for years and takes many forms‚ it is harming our environment and killing us slowly; in order to solve this problem the people of the world need to start
