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 is the…

the wave, depends on the wavelength of the wave that is absorbed. The reason we can see certain visible light is because the matter the waves hit reflects that wave, and absorbs all of the others light waves of different wavelengths. Visible light is emitted from nearly everything in the universe. Experts can detect visible light waves through polarized lenses, telescopes, and space shuttles. The light rays from the Sun hit Pluto’s outer surface. Depending on the wavelength, most of the light…

spectra of a species are put together, they form the continuous spectrum. A continuous spectrum is when the wavelengths are present within a given limit. For this reason, a rainbow has the all seven colors and considered to be a continuous spectrum. They are formed when hot objects emit electromagnetic radiations at all the wavelengths. In contrast, line spectrum has only few lines and wavelengths. For example, a colored compound is visible to our eyes in that certain color because it absorbs…

used in majority of experiments, they were used to identify spectrophotometric wavelengths (SW) between cancer cells (CC) and healthy living (HL) cells. These were used in comparison with serial dilutions containing…

Namely, Azulene absorbed a much higher wavelength, 576.0nm, compared to naphthalene’s absorbance of 309.3nm. This was due to differences in molecular orbitals. Naphthalene, being a benzenoid compound, had identical electron densities for its HOMO and LUMO. Azulene instead had different HOMO and…

The Effect of Varying Wavelengths on Photosynthesis of Spinach Introduction The rate of photosynthesis changes based on the light that the spinach is exposed to. Knowing the wavelengths of light that spinach is most likely to photosynthesize would help in knowing what light to expose spinach to, to ensure that it grows the best. When exposed to varying wavelengths, rate of photosynthesis varies as well. Wavelengths of green light, red light, blue light, and light without a filter change the rate…

Color skepticism is the belief that nothing truly possesses colors, since they are merely appearances to the perceiver. Although this is a sole belief on its own, there are many ways in which people have attempted to prove its validity. Some points of view include considering the scientific process behind the perception of color, while others, through a scientific lens, concentrate on what color really is, including its potential properties. However, I believe that the theory that is the most…

characteristics such as wavelengths and frequencies (Lucas, 2015). The distance between two high points (known as peaks) or low points is known as wavelength and is measured in nanometres (nm). Frequency is the number of waves that pass a specific location in a certain period of time and is measured in hertz (Hz). The larger the wavelength, the smaller the frequency and vice versa. UV light is on the Electromagnetic Spectrum which is a large scope of different wavelengths and frequencies. Its…

We stored the samples of the bacteria with a steady light source in a consistently cool temperature which will allow us to keep a consistent environment. Each different colored light bulb gives off different wavelengths which is what will be the difference in the results. An experiment was set up to examine the independent variables, which are the colors of light, temperature and pH, the dependent variable of our experiment is the motility of the Euglena cells…

The purpose of this experiment was to use aldol condensation methods to synthesize colored cyclopentadienone and then UV/VIS spectrophotometry to characterize the dienone structure synthesized. The information gathered from the UV/VIS analysis was then compared to a computer model of the desired product to analyze the optimal 3D structure of the dienone. The base catalyzed condensation reaction was used to form the product for analysis, followed by vacuum filtration to recover the product. Both…
