How does the Wavelength affect the Refractive Index? The aim of this experiment is to investigate the relationship between the refractive index and the wavelength. We will be testing 5 different wavelengths: 630nm (red)‚ 570nm (yellow)‚ 532nm (green)‚ 445nm (blue) and 405nm (violet). Figure 1 Figure 1 What is the refractive index? The refractive index is the measurement of how hard it is for light to pass through a certain substance‚ thus affecting the speed of light. By knowing the

SCIENTIFIC REPORT ON THE EFFECT OF WAVELENGTH ON PHOTOSYNTHESIS Red wavelengths will increase the rate of photosynthesis to a greater degree than blue or green wavelengths and thus will be the most optimal for plant growth. This hypothesis will be tested under laboratory conditions using silver beet extracts and DCPIP under different wavelengths and assessing the photosynthetic qualities using a spectrometer at 605nm. Photosynthesis is the process by which the suns visible light (electromagnetic radiation)

Comparing Wavelengths In The Electromagnetic Spectrum Gamma rays have the smallest wavelength in the electromagnetic spectrum‚ there is only 0.03 nano meters between the peak of each wave as is shown in this diagram. There is a universal speed that electromagnetic waves travel at which is 300m/s and this means that the wave frequency depends on the wavelength. The wave frequency for gamma rays is 300/0.03=10000hz. Gamma rays are produced by violent events in the universe such as supernovas and

draw energy from the sun and use it to form starch molecules. The process by which this happens is called photosynthesis and results in the formation of oxygen and glucose. Plants take in carbon dioxide‚ water‚ and light then release oxygen back into the air. This process happens because of the movement of hydrogen to the hydrocarbons that are produced during photosynthesis. The discovery of photosynthesis is attributed to Dutch scientist Jan Ingenhousz who was the first to find that light is necessary

(1) I think that the Internet does not contain reliable information. (2) The Internet‚ a technological breakthrough in the twenty-first century‚ contains many invaluable‚ pixelated advertisements that are not necessary for the society. Although it is necessary to advertise in order to expand a business‚ there are many advertisements that do not belong on a certain page. (3) For example when I am focusing on finishing up a research‚ there are many pop-up advertisements that appear out of nowhere.

Abstract on Determining the Photosynthetic Activity in Plants Using Different Wavelengths of Light using Chromatography and a Spectrophotometer In this experiment‚ the separation of particular pigments‚ contained within a fresh spinach leaf‚ were examined. Paper chromatography is the process of separating certain molecules‚ or pigment molecules‚ based upon their polarity. Four different pigments were examined from the spinach leaf: chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and carotene. Based

in the genres of country‚ blues‚ rock and hip hop music. Amongst these genres‚ there are also subgenres that display these differences as well. By observing a variety of songs‚ we are able to hear and distinguish between these genres. In country music‚ we can compare Jimmie Rodgers’ “Blue Yodel No 1 (T For Texas)” to Rednex’s “Cotton Eye Joe”. Jimmie Rodgers is one of the first country singers and is also known as “The Father of Country Music”. In his “Blue Yodel No 1 (T For Texas)” song‚ he only

BULLYING BOSSES 1. How does workplace bullying violate the rules of organizational justice? Bullying is inappropriate occurrence that affects one or more persons against another or others‚ at the workplace and consequences could be mental and physical. All employees including supervisors and upper management might be involved in bullying behavior either intentional or unintentional. Workplace bullying can violate the company rules through verbal bullying‚ gesture bullying‚ physical bullying
