    All Colors of the Visible Spectrum Grow Salvia Splendens More Efficiently than Red or Green Light on Its Own By: Diego Prado, Morgan Miller, Cody Holland, and Jonathan Ruppel Introduction The hypothesis for lab 5 was that plants that do not receive red light will perform photosynthesis less efficiently than those exposed to light of all wavelengths. The findings for that lab were that the plant that received all colors grew the most. The experiment was done again, but this time the algae was changed to a flower. In this experiment, the new hypothesis is that red is better than green on its own for growing salvia splendens, but all of the colors on the spectrum will work more efficiently together. The equipment and reagents used were six…

    These tools are extremely useful in gauging the wavelength of visible light, however due to shifting during reading, as well as possible shifts to the interior chart, it is likely that a great amount of error exists in the accuracy and precision of the instruments. Furthermore, the values of the wavelength are up to the discretion of the readers, meaning human error plays a role in the legitimacy of the results. There is little discrepancy between the values of the wavelength scale, and turning…

    The alternative hypothesis (H ₐ) states that trees at Mark Twain National Forest exhibit lower visible radiation values than trees at the Columbia Cemetery. The results were tested at the 5% and 15% significance level. The 5% level is the most commonly used level in statistical testing, while the 15% level is less accepted, it is not the most commonly used level because of the greater possibility (15%) the difference in results is by chance. The results of this test are significant because an…

    will fall on their autotroph tendencies through photosynthesis while if there is a food source but no true light source they will fall on their heterotroph tendencies. Euglenas show positive photo-taxis due to their ability to preform photosynthesis; this unicellular flagellate uses its “eye” to gravitate towards its best chance of being able to be autotrophic. As we observed the microscopic bacteria under several different microscopes, it was clear to see that Euglena does not have a cell wall,…

    Both IR and UV spectroscopy are methods of measuring the wavelengths absorbed by a tested material. IR spectroscopy measures the absorbance of the tested material in the infrared spectrum, the section of the electromagnetic spectrum with a lower frequency than that observed in the visible light spectrum. Conversely, UV spectroscopy measures the absorbance of the tested material in the ultraviolet spectrum, the section of the electromagnetic spectrum with a higher frequency than that observed in…

    Light Color and Photosynthesis Rate Introduction: How do the wavelength of visible light affect photosynthesis? Photosynthesis, a process used by plants and other organisms to convert light energy into chemical energy that can be released later to fuel the organisms’ activities, depends upon the absorption of light by pigments found in the plant leaves. Pigments, such as chlorophyll and carotenoids, absorb and reflect light based on the wavelength of light. To be more explicit, photosynthesis…

    This was when there were a series of different light bulbs that had to be observed on, off, and though a diffraction grating. (Sanders, 2). The other part of this section that was not described in Table 5 was the part with the array of LED lights. The observations were made through a diffraction grating as well and the light that was visible was in a continuous fashion. Let’s start with discussing the difference between experimental and calculated values of the wavelengths. In just about every…

    Lactose had 1.7 mL of CO2 at 30 minutes and remained constant not gaining any CO2 at 40 minutes resulting in 1.7 mL of CO2. In the second experiment my hypothesis stated the rate of photosynthesis is dependent on the wavelength (color) of light absorbed. The rate of photosynthesis can be measured by the amount of oxygen produced from various wavelengths of light in the color spectrum. The graph generated using various wave lengths in the visible light spectrum supports the hypothesis by…

    and that gas captures the infrared red which causes global warming Three scientists in the 19 century have studied infrared radiation and its effects on global warming. A German astronomer, Frederick William Herschel, discovered infrared radiation on February 11, 1800. Herschel used a prism to separate the different wavelengths and noticed that the wavelength with the highest temperature was beyond the red visible light portion of the visible light spectrum. This means that infrared radiation…

    wavelengths (red) is lower than for the shorter wavelength (violet). This leads to a large angle of refraction for the longer wavelengths than shorter wavelengths. When light emerges from the other side of the prism, we see the various wavelengths dispersed to show different colors of the spectrum. Fig.No.2.10 - Dispersion of Light 2.5. Behaviour of Light: Just there for…
