Wavelength

My hypothesis claimed that if seedlings are exposed to larger wavelengths of light, then their mass will gradually increase because of the greater amount of nutrients reaching the seedlings. The data provided during the experiment proves this hypothesis incorrect. Group D received 150 micrometers of light, which was the greatest amount of light for any group. According to the hypothesis, this plant would grow the most of the six groups. This, however, wasn't the case. In fact, Group D was among…

light travels at the same speed but each colour has a different wavelength and frequency. Before I go on to…

spectrum of chlorophyll a, chlorophyll b, carotene, and xanthophyll to determine the range of wavelengths of light absorbed by the molecules. It was predicted within the Spinacia oleracea extract, chlorophyll a and…

the electrons begin to return to their original energy level, energy is released as light, coloring the flame (“Flame Tests”, 2005). And as energy increases, frequency increases, but wavelength decreases. The color each chemical turns the flame depends on the light energy’s wavelength. For example, higher wavelengths (around 700) are colors such as red and orange, and lower ones (around 400) appear blue and violet (Timberlake, 2014). This denotes that light energy that gives off warmer colors…

used to focus light from the visible part of the electromagnetic spectrum. This is the variety of wavelengths / frequencies that radiation extend to. The smaller the length of the radio wavelength, the larger the Frequency (Hz) of the object is, as seen in the picture above, with a radio wavelength having the largest wavelength and an atomic nucleus having the smallest wavelength. Different wavelengths produce a different sort of radiation, and the only radiation that our…

procedure in order to determine the minimum number of wavelengths that are needed to match any other wave length in the spectrum. The procedure, should reveal three different types of colour deficiency. (Put citation…

will absorb all of the wavelengths, except for one group. This group of wavelengths is then reflected off of the objects. The cones and rods in our eyes will then pick up this wavelengths and then the brain sees them as “color”. The reason that solutions have colors is because electrons in the chemical’s 4d orbital are jumping around at different rates. These different rates are what gives the solutions different colors. Phosphoric acid is the chemical whose wavelength absorption is being…

to determine the maximum absorbance wavelength Figure 1. Cuvette #6, with 5ml of distilled water, acted as a blank to recalibrate the spectrophotometer to 0.000 absorbance between changing wavelengths.…

electromagnetic spectrum in order to analyze the results of the techniques used in this experiment. When one notices the color of an object, they are observing the wavelengths of visible light – 400 nm to 750 nm approximately…

stock solution was water in a test tube. The concentrations used were 0.139 mg/mL, 0.111 mg/mL, 0.083mg/mL, 0.057mg/mL and 0.028 mg/mL. There were two lots of each concentration made. The spectrophotometer was set at the previously calculate peak wavelength of 409mn and zeroed with deionised water. A cuvette was filled with 0.139 mg/mL and the absorbance was measured, then again with the same concentration from the other test tube and an average was calculated. This was repeated for each…
