understand what the dispersion of white light through a prism is. In simplest terms‚ the dispersion of white light is the process white light passes through a transparent triangular prism. Once the white light strikes the surface of the prism‚ it is refracted‚ which in scientific terms means that the light is deviated from its original path. At the point of refraction‚ the white light is separated into the 7 different color components that make up white light: red‚ orange‚ yellow‚ green‚ blue‚ indigo

darkness. NOT thinking of “Turn on the lights!” Do you know the feeling of having to watch a candle flame go until the wax puddle takes over the form of the candle. Yes‚ i know what its like to be without light. My name is Ruby Jewel. I lived in Lower South Alabama in 1941. For the longest I had no light whatsoever. I just couldn’t wait until that day where light would be my new friend. I knew it would be here soon. I just had that feeling in my gut. When my lights were on for the first time of my life

Light Intensity Characteristics of Photocells The photoelectric effect is defined as the emission of electrons from a material by visible light. The cadmium sulfide photocell is used to act as a conductor once exposed to light‚ allowing light to travel through. However it also acts as an electric resister (an opposition to a current flowing in a circuit) once not exposed to light. The photocell serves today ’s cause in a sufficient manner. It is used for a variety of reasons but it is mainly

Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of

that particular Sunday evening. The climbers‚ John and Mary had reached the tops of the cliffs as the sun was setting. They looked over the town to one side and the water on the other. The whole scene appeared strikingly beautiful in the late evening light‚ for it was sunset. Their hearts began to fill with emotions as the vast open sky started to turn from a baby blue to an autumn red‚ the clouds changed from cotton white to a flaming yellow orange giving the clouds a fluorescent

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

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

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

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
