Radiant Energy Essay

891 words - 4 pages

Introduction
The methodology for this experiment required a lot of careful measurement and calculations. The procedure consisted of many detailed steps to ensure accuracy when recording measurements. This experiment was carried out in an enclosed, darkened room because the the nature of the experiment requires a controlled temperature. Carrying out eight trials for each color of construction paper was a more accurate way of collecting a large quantity of data. In this experiment there were five groups of material (color) and eight experimental units in each group. There was a total of forty sheets of construction paper used; eight sheets of each of the five colors. The reason for testing ...view middle of the document...

There are five groups of differently colored construction paper (white, black, red, blue, and yellow), with 8 experimental units in each group. The paper’s dimensions are 8.5” x 11”. There will be eight trials conducted, and there will be new experimental units used for each trial to prevent change in pigmentation due to the constant exposure to a strong light source.

Statistical Analysis
Null hypothesis: Each color tested will have the same point of equilibrium of absorption of radiant energy. The statistical testing that will be done to analyze the data collected is the calculation of standard deviation, and from that the creation of a bell curve. The use of a least squares regression line will also be implemented in order to determine the point at which equilibrium is reached for each color of paper.

Methods/Procedures
The steps for preparation are as follows: Set up the table at the experiment site. Wipe it down with a clean washcloth. Set up the sun lamp directly above the middle of the table. Place an experimental unit from each group on the table. Use the infrared thermometer to take basal temperatures for all experimental units, and record those measurements.
The steps for experimentation are as follows: Take note of the temperature of the room at the start of the experiment. Once the basal measurements are taken and recorded, take all of the sheets of paper from the table, except for the white sheet, which should be left directly underneath the sun lamp. Turn off the lights in the experiment site, turn on the sun lamp, and start the timer. Every 20 seconds, use the infrared thermometer to measure...

Solar Energy- The true Power of the Sun

1029 words - 5 pages (Lsa.colorado.edu, 2014). The matter which is lost, is actually emitted into space as radiant energy (Lsa.colorado.edu, 2014). This follows the Law of conservation of energy. Only a small portion of that radiant energy produced by the sun reaches the earth. About one part in two billion (Lsa.colorado.edu, 2014). Even this one part is an enormous amount! The main question asked is , where does all of this energy go? 15 percent of the energy that hits the

Renewable Energy

870 words - 3 pages harnessed and the sun isn’t going anywhere, best of all, it’s free. At present, the most common means of harnessing solar power is the utilization of a system involving a series of solar panels and storage batteries. The panels collect the radiant light and store the captured energy in the batteries. For as long as engineers have designed buildings, they have used solar energy. They have taken advantage of the sun to ensure the comfort of the people

What Is Solar Energy Solar energy is defined as the radiant energy emitted by the sun. This source of energy is constantly accessible and can provide immeasurable amount of free energy depending on the size of the solar panels being used. By providing electricity, this renewable source of energy helps power tools

Solar Energy

731 words - 3 pages fuse to become one helium atom. The helium atom contains less mass than the four atoms that fused, so some matter is lost. This lost matter is released into space as radiant energy. Solar energy has changed life significantly. Back in the day, people had to use candles and lanterns to produce light. Now, because of solar energy we have electricity, so we don’t have to go through trouble for just a little bit of light. I expect that in the years

The Process of Photosynthesis

1237 words - 5 pages Photosynthesis is the process undergone by plants consisting of a series of chemical reactions that require four factors; water, carbon dioxide, radiant energy and temperature using chlorophyll molecules to trap radiant energy from the sun resulting in the making of glucose and oxygen as bi-products. The process of photosynthesis provides plants with the food and energy they need to grow. Plants that produce their own food are called

Factors Affecting Photosynthesis

803 words - 4 pages carbon dioxide are essential for starch production in plants. Chlorophyll, light and carbon dioxide are required for starch production in a leaf because chlorophyll captures light-energy from the sun and converts it into foods such as glucose and starch and if light is not present, chlorophyll cannot capture radiant-energy from the sun.
